What the Overloop interface shows

Screens captured in a signed-in Overloop account on September 13, 2026. Each caption identifies the controls we observed.

01 Inspect the autopilot settings

02 Check days, hours and time zone

03 Inspect the import steps

We did not run a prospect search, launch a campaign or import a file. These screens do not establish data quality, outreach results or a successful end-to-end import. Source: app.overloop.ai

Check the workflow during your trial

1. Use a small sample you are allowed to process and accounts you control. Keep campaigns paused; in Overloop, leave both autopilot switches off.
2. Apply the same targeting criteria in each shortlisted tool. Record returned fields, relevant contacts and credits used.
3. Draft one sequence without activating it. Check the audience, message edits, days, hours, time zone and reply ownership.
4. If migration is required, use an authorized test file. Check field mapping, duplicates and exclusions, then inspect the preview before proceeding.

Use the plan that can run your required sequence as the price baseline. Contact sourcing, sending capacity, mailboxes and team access are separate requirements even when a vendor bundles them.

Publisher disclosure: Overloop publishes this guide and is our first recommendation for small B2B teams that want prospect sourcing, email and LinkedIn in one workflow. The other options address specific requirements. Recommendations use public vendor sources; we did not run a comparative product trial. Method and dated sources.

Prices are public list prices before tax, read on September 12, 2026. "Entry price (annual)" is the displayed monthly equivalent when billed annually, on the cheapest plan that still runs a cold email sequence. A low entry price is not a low total cost once data, mailboxes, warm-up and seats are added.

Pick by team size, volume and deliverability need

Start with the channel mix, then compare users, contact volume and sending controls. Those requirements determine which plan belongs in the shortlist.

Email plus LinkedIn: compare Overloop, lemlist Multichannel and Reply.io Multichannel if one seller needs to coordinate both channels around the same prospect. Check the included LinkedIn account, source-data allowance and CRM integration scope. Email only: Smartlead, Saleshandy and Instantly are useful starting points when mailbox operations and sending capacity are the main requirement. Channel fit comes before the cheapest entry price.

1. How many people need a login?

Seat and workspace pricing scale differently. Check included team access on Smartlead, Saleshandy, Snov.io and Woodpecker, and multiply the per-user price on Overloop and Apollo by the people who need access. lemlist and Reply.io use different billing models across their plans.

• One or two people: compare the entry plan against your contact, channel and mailbox requirements. A low seat count does not remove data or infrastructure costs.
• Three to ten people: compare the full seat bill with a workspace plan that includes enough users. Saleshandy Pro lists ten users; check the data and send allowance as well.
• An agency with client sub-accounts: inspect Smartlead, Reply.io and Woodpecker for their documented agency structures. Client fees, white-label access and account isolation differ.

2. How many emails, and how many new contacts?

Send volume and contact volume are separate meters and entry plans cap both. Count the new people you contact each month, not the messages, because most of these products bill on the former.

• Under 5,000 emails a month: check unique-contact limits and mailbox capacity as well as the send allowance. An entry tier can fit the email count while lacking enough contact data.
• 5,000 to 100,000 a month: compare the exact sending cap. Smartlead Pro lists 90,000 emails and Saleshandy Pro 100,000; a team needing the full 100,000 would need a higher Smartlead tier.
• Above 100,000 a month: evaluate sending infrastructure and plan limits directly. Smartlead and Instantly publish tiers for these volumes; confirm the mailbox setup and operational support required.
• Volume that swings by season: compare contacted-prospect pricing, such as Woodpecker's, with fixed plans. Check minimum charges and downgrade terms before assuming a quiet month costs less.

3. What do you need to protect the domain?

Compare warm-up, verification and mailbox rotation together with authentication and sending controls. These features are bundled differently and do not guarantee inbox placement.

• Warm-up bundled: Snov.io, Instantly, Reply.io and Woodpecker. Smartlead charges $59 a month for it on its two lower tiers.
• Verification bundled: Saleshandy includes it inside its lead credits, Smartlead meters verified emails per plan, lemlist bills five cents per address.
• Mailbox rotation: standard on Smartlead, Instantly and Saleshandy. On GMass it is the top tier only.
• A fresh domain: use the trial to inspect authentication, pacing and pause controls. A trial length or fixed warm-up calendar does not establish readiness to increase sending volume. Read our email warmup guide before you start a trial clock.

1. Overloop: best for small B2B teams that want data, email and LinkedIn in one tool

Best for: a two-to-ten person B2B team that wants to find a prospect, write the sequence and add a LinkedIn step without buying three products.

Overloop is our product and our first recommendation when your B2B team needs prospect sourcing, an email finder and email plus LinkedIn sequences in one platform. Compare its per-user cost and credit allowance with the number of contacts and connected email accounts your team needs; an email-only platform may fit a mailbox-heavy workflow better.

Pricing on September 12, 2026. Starter is $69 per user per month with 250 credits per user, one connected email account and three active campaigns. Growth is $99 per user per month with 500 credits, three email accounts, ten active campaigns, the HubSpot and Pipedrive integrations and REST API access. Enterprise is quoted and adds Salesforce, a dedicated IP and granular roles. There is no annual toggle: the published price is the price. The trial runs seven days.

The limit that bites: a five-seat team pays five times, where Saleshandy, Snov.io and Smartlead charge once. One connected mailbox on Starter is thin for anyone rotating domains, and seven days is the shortest trial here. Overloop does not document a native phone channel on its current pricing page.

If you want the product page rather than the roundup, it is cold email software.

2. Smartlead: best for agencies and high-volume mailbox operations

Best for: agencies and in-house teams running many sending domains at once.

Smartlead sells sending capacity, not seats. Every plan advertises unmetered email-account connections on a flat workspace fee, which is why lead-gen agencies default to it. Sequences, inbox rotation, a master inbox, sub-accounts and white-label are all in the box.

Pricing on September 12, 2026. Base is $39 per month, or $32.50 billed annually, for 2,000 contacts, 6,000 emails and 2,000 verified emails a month. Pro is $94, or $78.30 annually, for 30,000 contacts and 90,000 emails. The tier labelled Unlimited Smart is $174, or $144.50 annually, and still caps sends at 150,000. Unlimited Prime is $379, or $314.60 annually, for 500,000 sends. Warm-up costs $59 a month on Base and Pro and is bundled above. CRM access is $39, calling $29, white-label $29 per client. A free trial exists; the page does not state its length.

The limit that bites: the plan names promise more than the quotas deliver. An unmetered mailbox count on the $39 plan still shares one 6,000-email ceiling, and warm-up costs more than the plan itself until the $174 tier.

3. Saleshandy: best value for a small team that needs data and sending together

Best for: a one-to-ten person B2B team that wants data, verification and sequencing on one invoice.

Saleshandy bundles the most at the entry point: a flat workspace price, sender rotation and pacing, and a monthly allowance of lead credits instead of a separate data subscription. One credit buys one verified work email, a phone number six. Manual LinkedIn steps fit inside a sequence; automated LinkedIn does not.

Pricing on September 12, 2026. Starter is $34 a month billed annually, shown as $408 for the year, or $41 monthly: 2,000 active prospects, 6,000 emails, 1,500 lead credits and one user. Pro is $76 annually, or $99 monthly, for 30,000 prospects, 100,000 emails, 4,000 credits and ten users. Scale is $149 annually, or $189 monthly, for 200,000 emails and 8,000 credits. On annual billing the full year of credits lands up front. The trial runs seven days.

The limit that bites: seven days is the shortest trial here and is tight once authentication and warm-up eat the first week. Automated LinkedIn is absent at every tier, so a multichannel team pays twice.

4. Instantly: best when sending and lead data are bought as one bundle

Best for: operators who want one vendor for mailboxes, warm-up and a lead database.

Instantly splits its pricing into four tabs, and reading the wrong one is the most common budgeting error in this category. Outreach sells sending, Credits sells data, Bundles sells both at a price that is not the sum. Mailboxes and warm-up are unmetered on every tier.

Pricing on September 12, 2026. On the Outreach tab, Growth is $47 a month, or $37.60 annually, for 5,000 emails and 1,000 contacts. Hypergrowth is $97, or $77.60 annually, for 25,000 contacts, and the monthly and annual cards show different send figures. Light Speed is $358, or $286.30 annually, for 500,000 emails. On Bundles, Starter is $94, or $85 annually, for 5,000 emails, 1,000 contacts and 1,500 credits; Scale is $194, or $175 annually, for 100,000 emails, 25,000 contacts and 5,000 credits; Agency is $555, or $500 annually. Standalone credits start at $47 for 1,500. The page advertises no free plan and no trial.

The limit that bites: $37.60 is the sending half only. Add data and you land on a bundle at roughly double, and with no published trial the first real test is a paid month.

5. lemlist: best for personalization, with a per-user cliff on multichannel

Best for: teams whose edge is the message itself: personalized images, video thumbnails and AI-assisted copy.

lemlist keeps the most distinctive creative layer in the category. It is also the only product here whose billing unit changes between its two main plans, which makes a naive price comparison misleading.

Pricing on September 12, 2026. The Email plan is $69 a month, or $55 billed yearly, priced per workspace with unmetered users and 50,000 emails a month. The Multichannel plan is $109 a month, or $87 yearly, priced per user, with five senders each. Contact data is not bundled: credits cost one cent each, so a verified email is five cents and a phone number twenty. Intent signals run from 20 credits for a website visit to 400 for LinkedIn engagement. The trial is 14 days on Multichannel.

The limit that bites: the step from Email to Multichannel is not $40, it is a change of model. A five-person team pays $55 a month on Email and $435 on Multichannel at yearly rates, with data outside both.

6. Snov.io: the cheapest flat-rate way to get data and sending on one bill

Best for: a bootstrapped team that wants a finder, a verifier, a sender, warm-up and a light CRM for less than one seat elsewhere.

Snov.io charges per workspace and includes team seats, which changes the arithmetic past two people. LinkedIn automation exists but sits outside the plan.

Pricing on September 12, 2026. Billing is monthly, quarterly at 5 percent off, or annual at 25 percent off. Starter is $39 a month, or $29.25 annually, for 1,000 credits, 5,000 recipients and three warm-up slots. Pro S is $99, or $74.25 annually, for 5,000 credits and 25,000 recipients. Pro M is $189, or $141.75 annually; Pro L $369, or $276.75; Pro Ultra $738, or $553.50. LinkedIn automation is a separate slot at $69 a month, or $62 annually. Phone and enrichment data use a token wallet: 10,000 tokens cost $200 once and expire after 90 days. The free Trial plan renews every 30 days with 50 credits and 100 recipients.

The limit that bites: the credit line, not the plan line. A thousand credits a month is about a thousand addresses, which a team prospecting seriously burns in two weeks. The free tier excludes integrations, bulk search, A/B testing, the API and export.

7. Apollo.io: best when the contact database is the reason you are buying

Best for: teams whose bottleneck is finding the right accounts, with sequencing as the second job.

Apollo is a database that grew a sequencer, and the pricing shows it: everything is metered in credits, and credits are what you are buying. Its free plan is the most generous entry point here and a legitimate way to test data coverage on your own ICP first.

Pricing on September 12, 2026. The free plan gives 900 credits per seat per year, released monthly, and caps sequences at two. Basic is $49 per seat a month billed annually, or $65 monthly, with 30,000 credits per seat released up front on annual billing. Professional is $79 per seat annually, or $99 monthly, with 48,000 credits. Organization is $119 per seat annually with a three-seat minimum. The Inbound module and the Advanced Dialer are each $119 per team a month billed annually. Paid tiers advertise a 14-day trial. Apollo's own structured data lists a different Professional price from the table a buyer sees; quote the rendered table.

The limit that bites: two sequences on the free plan makes it a data trial, not a sending trial, and database size is a marketing number. Test coverage on 200 of your own target accounts before committing a year.

8. Reply.io: best channel coverage, hardest pricing page to read

Best for: a team that wants LinkedIn, calls, SMS and semi-automated WhatsApp inside one sequence, plus agencies needing multi-workspace billing.

Reply.io covers more channels than anything else here and prices them in more ways. The model changes shape halfway up the ladder: below 10,000 active contacts you pay per user, at and above it a flat fee with unmetered users.

Pricing on September 12, 2026. Email Volume is sold by active contacts a month, where an active contact is one first-step email plus its follow-ups. On annual billing that is $49 per user at 1,000 active contacts, $69 at 3,000 and $89 at 5,000, then flat fees with unmetered users: $159 at 10,000, $259 at 25,000, $459 at 50,000 and $899 at 100,000. Multichannel is $89 per user annually with ten mailboxes, or $99 monthly with five. Both include warm-up, 50 live-data credits a month and up to 200 visitor reveals. On Email Volume, LinkedIn automation adds $69 per account and calls with SMS $29. Multichannel includes one LinkedIn account and the calls/SMS channel per user; do not add the Email Volume channel charges again. The Jason AI SDR starts at $500 a month, and Agency Core at $210. The trial is 14 days.

The limit that bites: compare the plan that contains your channels. Three Multichannel seats with their included LinkedIn accounts cost $267 per month on annual billing, before data or infrastructure extras. Email Volume plus LinkedIn is a different configuration, not the price of Multichannel.

9. Woodpecker: best usage-based pricing, if you can get a number out of it

Best for: lumpy outbound volume, agencies with a variable client roster, and anyone who resents paying for a seat that sat idle in August.

Woodpecker meters what you consume: contacted prospects per month, where one person contacted five times counts once. Team members and email accounts are not metered, and the base slider position includes 16,000 emails a month, four warm-ups and 100 Lead Finder credits.

Pricing on September 12, 2026. We could not publish Woodpecker's plan prices. The page renders its totals in the browser from a slider, and every price node served to us was empty, so any figure here would be invented. What the page does publish as static text is the structure and the add-ons: a contacted-prospects slider from 500 to one million a month, annual billing advertised as 33 percent cheaper, and twelve currencies. LinkedIn outreach is $29 a month per connected account, an extra warm-up $5, a Google or Microsoft mailbox $6, a mailbox elsewhere $4, a dedicated server $59, integrations and API access $20, and the agency panel $27 per active client. Lead Finder credits start at $10 per 500. The trial is 14 days.

The limit that bites: you cannot budget Woodpecker from its pricing page, only from its calculator, and the add-on sheet is long enough that a mailbox-heavy setup can double the slider figure.

10. GMass: the cheapest way to send cold email, if you live in Gmail

Best for: founders, recruiters and solo operators who send from one Google Workspace account and do not want a second application.

GMass is a Chrome extension that turns the Gmail compose window into a sequencer. Merges run from Google Sheets, replies land in the thread you already know, and follow-ups stop when someone answers. That is also its ceiling: it inherits Google Workspace sending limits and is not the tool for twenty domains.

Pricing on September 12, 2026. Individual plans are priced per Google account. Standard is $29.95 a month, or $20 at $249 a year. Premium is $39.95, or $29 at $349 a year. Professional is $59.95, or $49 at $599 a year. Team bundles of the Premium plan come in fixed seat counts: five users at $145 a month annually, ten at $245, twenty-five at $604, fifty at $1,125 and a hundred at $1,833. Every tier advertises unmetered emails, contacts, campaigns and verification, footnoted as depending on individual account configuration. Sequences, A/B testing and the API start at Premium; inbox rotation is Professional only. The page offers a free call to action but states no trial length.

The limit that bites: Standard has no follow-ups, so it is not really a cold email plan. The real product starts at Premium, and the advertised sending ceiling is Google's, not GMass's. We could not capture a current public page for this product, so this section carries no image.

Check what the subscription includes

Confirm five things on the plan you would buy: the billing unit, sending and contact limits, data credits, deliverability controls, and trial or export terms. A sending plan can fit a team that already owns its data; a sourced-contact workflow needs both costs in the budget.

What to budget for a three-person B2B sales team

Use the same requirements when requesting a quote: three users, six connected mailboxes, 1,500 newly sourced prospects with valid emails per month, around 6,000 sends, and warm-up. Decide separately whether LinkedIn is required. The examples below distinguish the platform bill from missing capacity; they are not equivalent all-in quotes.

Sources rechecked September 13, 2026: Overloop plans and credit rules, lemlist plans and enrichment credits, and Reply.io plan inclusions. These subtotals exclude tax, domains and mailbox hosting. Keep annual commitments visible rather than comparing them with cancel-anytime monthly prices.

Before switching, export suppression lists first, preserve verification status and custom fields, and rebuild one representative sequence with its sending windows and reply handling. Check CRM field mapping and the destination of replies before moving the rest of the team. Our Apollo migration checklist gives a practical example.

No cold email software can promise the inbox

None of these ten can guarantee inbox placement, and any vendor implying otherwise is selling something it does not control. A platform can check authentication, pace sends, rotate mailboxes, warm accounts, verify addresses and process unsubscribes. It cannot control recipient complaints, stale lists, weak relevance, a damaged domain history, or the filtering decision made at Gmail, Outlook or Yahoo.

The floor is published and it is not optional. Google requires every sender to personal Gmail accounts to authenticate with SPF or DKIM, keep valid forward and reverse DNS, transmit over TLS and keep complaints low. Senders of roughly 5,000 or more messages a day to Gmail must also use both SPF and DKIM, publish DMARC, align the From domain, support one-click unsubscribe and keep the reported spam rate below 0.3 percent. Read Google's email sender guidelines and its sender-requirement FAQ, then check the equivalent rules for every provider on your list.

Is cold email legal, and where does that change your shortlist

Cold email to a business contact is lawful in most major markets when it is done correctly. The rules are about consent, identification and opt-out, not about which software you bought. In the United States, the CAN-SPAM Act requires accurate headers, a valid physical postal address and a working opt-out honored promptly, but no prior consent. In the European Union, direct marketing to a business contact generally relies on legitimate interest under Article 6(1)(f) of the GDPR, which requires a documented balancing test, a privacy notice and an immediate route to object, with stricter national rules in several member states. This is a product comparison, not legal advice.

For the shortlist the consequence is narrow but real: check each vendor's data processing agreement, its documented processing regions, and whether opt-outs are enforced across every campaign in the workspace rather than one at a time. See our guide on whether cold email is illegal for the full treatment.

What did not make the list, and why

Three categories were left out deliberately. Email marketing platforms such as Mailchimp or Brevo are built for opt-in lists and will suspend an account for cold sending. Enterprise suites such as Outreach and Salesloft do not publish prices a small team can act on. Mailshake was the closest omission: a competent per-user sender at $25 a month on yearly billing, but it collects payment up front with no free trial, and one connected mailbox on the entry plan is thin for cold email in 2026.

Bottom line

For a small B2B sales team that needs sourcing, AI-assisted messages, email and LinkedIn steps in one campaign, Overloop is our first recommendation. Compare its credit capacity and CRM scope with your actual workflow. If you already own the contact data and mainly need many sending mailboxes, compare the email-only platforms on those requirements. Overloop publishes this guide, and this recommendation reflects that specific product fit.

Start with the workflow you need to run. For email-only campaigns across many domains, compare Smartlead, Instantly and Saleshandy on contact caps, sending capacity and mailbox operations. For contact data plus email on one subscription, examine Saleshandy and Snov.io against your required reveals and team access. For personalized creative assets, inspect lemlist. If finding the account is your main bottleneck, use Apollo's free plan to check coverage on your own ICP before selecting a paid plan.
