What is Instantly?

Instantly is a tool for cold email campaigns, meaning B2B acquisition emails sent in series to recipients who don't know you yet and haven't requested anything. It gained recognition for its pricing model: you can connect any number of sender inboxes without paying per account, which makes scaling affordable.

‍

Agencies and sales teams use it for outbound sequences featuring automatic follow-ups, inbox rotation across multiple domains, and built-in email warm-up. It also includes a lead database with over 450 million B2B contacts, which you can filter by industry, role, and region and pull directly into campaigns.

‍

Compared to Lemlist, it lacks multichannel depth with LinkedIn steps, and compared to Apollo.io, it doesn't offer the broader sales ecosystem. Furthermore, it's important to note: cold outreach via email is legally sensitive in Germany; the UWG (Unfair Competition Act) and GDPR set strict limits that the tool does not exempt you from.

‍

Recommended for B2B teams with precise targeting and legal safeguards who are serious about scaling outbound efforts. Those looking for multichannel sequences with LinkedIn steps should consider Lemlist instead.
