That’s where Warmup Inbox comes in—to automate sending and receiving emails from your inbox in a very natural and steady pattern.

This will help in establishing your email account as a credible one, so your emails are more likely to land in the inbox rather than the spam folder, increasing your chances of success in email marketing.
