Frequently asked questions

What topics does the Overloop blog cover?

The Overloop blog covers six pillars: AI B2B sales prospecting, AI multi-channel sequences, LinkedIn automation, B2B contact databases, email verification and deliverability, and tool comparisons. Articles are practical playbooks: how to write cold emails that get replies, build prospect lists, run LinkedIn plus email sequences, avoid spam, and pick the right outbound stack.

Who writes for the Overloop blog?

Three in-house operators run the editorial: Vincenzo Ruggiero, Nathalie Saikali, and Nicolas Finet (CEO). Every article is tested on real Overloop campaigns before publishing, with 47,000 plus emails sent and six months of measured data behind the recommendations. No outsourced ghostwriters, no paid placements, no AI slop.

How often is the blog updated?

Fresh articles ship weekly. Existing articles are reviewed quarterly to keep tools, prices, and tactics accurate. The latest articles section on the homepage surfaces what was just published or refreshed. If a tool gets acquired or a tactic stops working, posts get updated rather than left to rot.

Are the tool recommendations sponsored?

No. Overloop runs zero paid placements in articles. Recommendations come from in-house testing on live campaigns. When Overloop is mentioned, it is because it is the tool the team uses. Comparisons with Apollo, Lemlist, Outreach, Instantly, and others are based on real usage, not vendor briefings or affiliate links.

What languages is the blog available in?

The Overloop blog runs in four languages: English, German, French, and Spanish. Each locale has roughly 20 articles, totaling around 80 pages. Hreflang tags link the localized versions, and articles are translated and adapted to each market rather than machine-translated. Italian is rolling out next.

How can I subscribe to new articles?

The newsletter card on the homepage collects emails for the weekly digest. Subscribers get the latest articles, tactical playbooks, and occasional cold email teardowns. No spam, easy opt-out, GDPR compliant. Signing up is the fastest way to get fresh outbound tactics without checking the blog manually.

What is Overloop?

Overloop is an AI-powered B2B sales prospecting platform. It combines a 450M contact database, AI personalization, and multi-channel outreach across email and LinkedIn in one workflow. Sales teams use it to build prospect lists, run sequences, and sync with Salesforce, Pipedrive, HubSpot, Slack, and Calendly. Owned by Sortlist, headquartered in Brussels.
