You craft compelling cold emails and launch a campaign, only to see your emails landing in the spam folders. Sounds familiar? 

If you have ever faced this issue and want your cold emails to land in your prospects’ inboxes, bypassi ng the SPAM folders, then this article is for you. Email warmup is a crucial process of building a good sender reputation and maintaining high-deliverability of your email accounts. 

There are lots of email warmup tools available to choose from. In this article, let’s check out the top 9 best email warmup tools for cold outreach in 2024 with detailed reviews. 

Understanding Email Warm-up

Email warm-up is a strategic process of establishing and enhancing trust with Email Service Providers (ESPs) by sending system-generated (automated) or manually crafted emails from a new inbox. 

The warm-up journey prompts responses (often automated) to showcase engagement to the ESP. This automated process lends authenticity to the email activity, gradually building trust with ESPs. Advanced email warm-up tools leverage AI and machine learning, orchestrating simulated business interactions that mimic genuine engagement, thereby tricking ESPs into recognizing legitimacy.

A proper warm-up isn't a rushed task; it's a gradual process spanning at least 2 weeks for a new inbox.
