Best Email Warm-Up Tools for Cold Emailing

Cold emailing is a double edged sword; on one hand it can help you generate extremely valuable leads with virtually no work, but if it’s not done correctly, your emails can land in the spam folder and all that time can be wasted.

One of the best ways to prepare for a cold email campaign is to warm up your email and domain to increase email deliverability. This used to be done manually by emailing back and forth with your friends, colleagues, and co-workers. The goal is to generate a ton of email activity and positive responses which boosts your domain’s reputation and increases the likelihood that your emails stay out of spam and land in the primary inbox. 

Nowadays, there are a variety of tools that can automate this process and that’s exactly what we’ll be covering today.

Our family at LeadLoft sends a lot of emails, so we’ve had plenty of time to test out nearly all of the email warming tools on the market - here are our 5 favorites.
