How to choose

Volume or relevance? For thousands of emails a day across many domains, pick a high-volume sender. For fewer, personalized emails from your own address, pick a tool that writes per person.
Do you need data? If you have no list, a tool with a contact database saves a separate purchase.
One channel or several? If LinkedIn matters to your buyers, check whether it's included or an upgrade.
Who does the work? Some tools are software you operate; others write and send for you with your approval.

FAQ

Questions founders ask.

What is the best cold email tool for startups?

It depends on volume. For founders sending personalized email from their own Gmail, with LinkedIn and SEO alongside, Distro is built for that. For high-volume sending across many inboxes, Instantly or Smartlead. For a contact database plus sequences, Apollo.io.

Is it safe to send cold email from Gmail?

Yes, at a human pace with a properly authenticated domain, relevant emails, a one-click unsubscribe, and follow-ups that stop on reply.

Do I need email warmup?

High-volume senders using new domains usually do. If you send a modest number of relevant emails from an established account, pacing and relevance matter more.
