Email Warm-Up Made Easy: How Boost Inbox Integrates with Any Email Provider


Sending cold emails is a difficult task, especially if the emails land in the spam folder. The good news is that there is a solution: email warm-up. This method improves your email deliverability and engagement rates.

A  study in 2024 by Boost Inbox showed that properly warmed-up emails can see open rates increase by up to 85.67% compared to cold emails sent from a new account.

In this blog post, we'll discuss the challenges of cold emailing, how email warm-up works, and, most importantly, how Boost Inbox seamlessly integrates with any of the email providers, making the process easy.

The Challenges of Cold Email Sending

You write an email just to have it disappear into the vast sea of unopened messages or, worse, designated as spam. This is a regular issue for those who send cold emails.

Email providers employ strict filters to protect the public, but these filters can often be a barrier for legal senders. Without a history of contact with the recipient's inbox, your email is in danger of being marked as spam or dropped to the promotions section.

How Email Warm-Up Works

An email warm-up is like building a relationship with email providers before making a significant request. It involves sending a series of low-risk emails to engage with your own domain before gradually increasing the sending volume.

This indicates to email providers that you are a reliable sender, improving the probability that your emails will be received in the primary inbox.
