Email warm-up was as simple as gradually sending more emails until you reached your daily volume target. Deliverability was much easier back then. Thus such an email-warming process was already enough.
That’s not the case nowadays. A proper email warm-up is now done by gradually raising the email volume AND having a high email engagement rate. Achieving both metrics demonstrates to the email providers that you’re a legitimate and interesting sender who deserves the inbox, not the spam folder.
Fortunately, email warm-up tools can help your email domain be recognized as trustworthy to email servers.
This blog has filtered the top 15 email warm-up tools to help level up your email marketing campaign. But before that, let’s explore what email warm-up is, how to do an email warm-up the best way (whether manual or automatic), and why it’s important.
What is Email Warm-Up or IP Warming?
Email warmup, also known as IP warming, gradually increases your email sending volume. Warming up your email address helps build a good email and domain reputation.
A warmed email address is one that has been sending and receiving emails or newsletters regularly.
Email warm-up aims to establish your campaign’s presence strategically with optimized deliverability. Once you have established a good email reputation, it will lead to an increased open rate. It results in improved clicks, leads, and reply rates.
If you decide to do an automated email warm-up, you will need the best email warmup tool you can trust and rely on. Any of these tools can fit your business perfectly:
