Cold Email Software for Data, Drafting, and Deliverability Controls
Run targeted B2B cold email from contact sourcing and address checks through reviewable copy, sequenced sending, and measurable follow-up.
Start free trialWhat is cold email software?
Cold email software helps a team source or import business contacts, prepare outreach, sequence follow-ups, pace sending, handle replies and opt-outs, and measure campaign behavior. It can support a controlled outbound process, but it cannot validate your offer, legal basis, mailbox reputation, or inbox placement for you.
Overloop's documented scope: a 450M+ B2B prospect database, email finding and verification, manual or AI-assisted email drafting, email and LinkedIn campaign steps, sending controls, reporting, and configured CRM connections. Your team still owns the audience, offer, factual review, sender setup, replies, qualification, and compliance decisions.

The video above is Overloop's published tutorial for creating a campaign. It shows the product workflow rather than a synthetic animation. Use the trial and current documentation to verify the editor, sending controls, data coverage, and handoff for your own setup.
How Overloop's cold email software works
Define the audience and exclusions
Your team sets the ICP, buying roles, locations, company criteria, current customers, competitors, suppression rules, offer, and campaign objective. Those inputs determine whether the workflow is relevant.
Source contacts or bring your own list
Search the advertised 450M+ B2B prospect database, add profiles through the Chrome extension, or import a file. Use the email finder and verification workflow, then test coverage and status quality against a representative ICP sample.
Draft, preview, and test the email
Choose manual or AI-assisted copy, edit the subject separately, preview a message sample with prospect variables, and configure an A/B variant where useful. Generated facts, relevance, tone, and recipient suitability remain your responsibility.
Configure the sequence and sending window
Build email-only or email plus LinkedIn sequences with delays and conditions. Set campaign days, hours, and timezone, then review each connected inbox's Smart Limit before launch.
Launch, monitor, and hand off
Approve prepared emails or enable Autopilot only after reviewing the audience and message setup. Monitor sent, bounced, opted-out, opened, clicked, visited, and replied states, then route replies and supported CRM activity through your team's operating process.
What Overloop controls—and what your team owns
| Layer | Overloop assists with | Your team remains responsible for |
|---|---|---|
| Audience and data | Database filters, imports, email finding, verification status, exclusion lists | ICP fit, lawful targeting, sample checks, deduplication, suppression decisions |
| Message | Manual or AI-assisted drafts, sample preview, subject editing, A/B variants | Offer, factual accuracy, relevance, tone, approvals, claims |
| Sender setup | Connected inbox settings and guidance for SPF, DKIM, DMARC, and a tracking domain | Mail provider, domains, DNS records, mailbox health, incident response |
| Sending | Schedules, queueing, daily Smart Limits, campaign steps and conditions | Appropriate volume, capacity planning, monitoring, pause and escalation rules |
| Replies and compliance | Reply, bounce, out-of-office and opt-out signals; reporting and configured CRM handoff | Buyer conversations, objection handling, qualification, legal basis, notices, retention and rights requests |
Published sending and deliverability controls
Deliverability depends on the sender, infrastructure, audience, message, recipient systems, and changing mailbox-provider rules. The controls below help manage that process; none is an inbox-placement guarantee.
| Control | Documented behavior | What to verify |
|---|---|---|
| Connected inbox | Overloop sends through the email account you connect; replies arrive in that inbox. | Provider support, ownership, reconnection process, reply coverage |
| Email Smart Limits | Enabled by default; a newly connected inbox starts at 50 emails/day and can adjust up to 250/day based on account signals. | Current limit per inbox, custom-limit risk, capacity across campaigns |
| Queue and schedule | Campaigns follow configured sending days, hours, and timezone. Current documentation lists one email every 30 seconds, capped at 120/hour per account before the daily limit. | Follow-up priority, queued work, timezone, provider limits |
| Authentication and tracking | Overloop documents checks and setup guidance for SPF, DKIM, DMARC, and a custom tracking domain. | Exact DNS records, alignment, rollout, ongoing authentication reports |
| Warm-up | The pricing page advertises built-in email warm-up through a network. | Current availability, operating method, mailbox suitability, results over time |
| Monitoring | Reports expose campaign and step-level activity including bounces, opt-outs, opens, clicks, visits, and replies. | Tracking choices, signal reliability, alerting, pause thresholds |
Review the current email Smart Limits, queue and schedule behavior, and deliverability setup guide before setting capacity. You can also inspect your domain with the domain health checker and review message signals with the email spam checker.
Plans, inboxes, campaigns, and credits
| Plan | Public monthly price | Credits/user | Connected email accounts/user | Active campaigns/account | Published integration tier |
|---|---|---|---|---|---|
| Starter | $69 per user/month | 250 | 1 | 3 | Basic integrations |
| Growth | $99 per user/month | 500 | 3 | 10 | HubSpot, Pipedrive, REST API |
| Enterprise | Custom price | 1,000 | Listed as unlimited | Listed as unlimited | Salesforce plus Growth integrations |
Credit and trial note: one credit is used to source a prospect and one to find a successfully validated email address. Sending emails, creating AI drafts, campaign enrollment, and contacting an existing stored prospect do not consume credits. A hard bounce is documented as triggering a credit refund. Overloop advertises a 14-day free trial with no credit card required. Check current pricing and allowances and the credit documentation.
Human review and Autopilot are different operating choices
Overloop lets a user choose AI-generated or manual email copy, preview a populated message sample, and edit the result. A user can approve prepared emails or turn on Autopilot for a configured campaign. That means the defensible control is campaign governance and review before Autopilot—not a claim that a person checks each individual email. Define who can activate a campaign, inspect samples, pause sending, and handle exceptions.
Reporting, opt-outs, and CRM handoff
Test at the step level
The sequence editor documents manual or AI email steps, subject editing, sample preview, conditions, delays, and A/B variants.
Monitor campaign states
Reporting includes contacted, bounced, opted-out, opened, clicked, visited, and replied states. Treat opens and clicks as signals, not proof of buyer intent.
Configure suppression
Settings include opt-out links and exclusion lists. Your team still owns notices, suppression rules, response handling, and legal requirements.
Validate the CRM handoff
HubSpot and Pipedrive are listed on Growth and Enterprise; Salesforce is listed on Enterprise. Supported fields and events vary, and Overloop's documentation says prospect replies do not sync back into HubSpot.
Is Overloop the right cold email workflow for you?
Strong fit
B2B sales teams, founders, and agencies that want prospect data, email finding, reviewed drafting, email plus LinkedIn steps, and reporting in one workspace.
Validate the sending setup
Test your mail provider, DNS records, connected-inbox behavior, Smart Limits, schedules, tracking choices, bounces, opt-outs, and replies before scaling.
Validate the economics
Model seats, credits, inboxes, active campaigns, sending capacity, domains, mail providers, and any specialist deliverability services you still need.
Consider a specialist email-only setup
If your brief centers on low-cost unlimited inboxes, ready-to-send domains, white-label client portals, or dedicated inbox-placement testing, compare specialist products and ask Overloop to confirm its current scope.
If your brief starts with a market-wide shortlist, use the AI email outreach tools guide. This landing explains Overloop's documented product scope rather than ranking the market.

Can Overloop guarantee inbox placement?

Does Overloop include email warm-up?
Overloop's pricing page advertises built-in email warm-up through a network. Verify current availability and operating details for your plan and mail provider. Warm-up does not replace SPF, DKIM, DMARC, responsible targeting, ongoing monitoring, or provider compliance.
Can AI write and send cold emails automatically?
Overloop supports AI-generated or manual email copy, sample preview, editing, approval, and an Autopilot option for configured campaigns. Before enabling Autopilot, your team should review the audience, offer, facts, tone, sequence, limits, exclusions, and exception process.
Does Overloop include contact data and email verification?
Overloop advertises a 450M+ B2B prospect database, email finding, and verification. Coverage, fields, status, accuracy, future validity, and inbox placement vary, so test a representative sample before scaling.
Does Overloop support LinkedIn and CRM handoff?
Overloop supports email and LinkedIn steps in one sequence. HubSpot and Pipedrive are listed on Growth and Enterprise, while Salesforce is listed on Enterprise. Supported fields and events vary, and Overloop's documentation says prospect replies do not sync back into HubSpot.
How does Overloop support opt-outs and GDPR requirements?
Overloop provides opt-out link and exclusion list settings and publishes GDPR guidance, a DPA, privacy information, and security controls. Your organization still owns lawful basis, targeting, notices, retention, access, objections, suppression, and opt-out handling for each campaign.
