Frequently Asked Questions
about SMTP warm up
What is SMTP IP reputation ?
SMTP IP reputation is tied up to your IP and email domain and is built up over time. It’s driven by how your recipients react to your emails.
It’s a measurement of your email sending practices that affect your inbox placement.
Typically, if you send a lot of emails that get reported as spam, your SMTP IP reputation will be affected and future emails will be more likely to land in spam or promotion tabs instead of the main inbox.
This is why it’s crucial to build a solid sender reputation over time to maximize reaching the inbox.
The better your SMTP IP reputation, the better your email deliverability.
How to warm up SMTP server ?
There are two ways of warming up a SMTP server : manually or automatically.
To warm up a SMTP server manually, you need to gradually increase the volume of emails you send over several days and weeks following a schedule.
Ideally, you also need to generate a high level of engagement (openings, replies, marking emails as important, removing from spam, etc).
Unfortunately, doing it manually is time consuming and less optimal than using an automated SMTP IP warm up service like MailReach.
MailReach warms up your SMTP automatically with a smart algorithm that handles dozens of parameters to maximize your SMTP IP reputation.
You just need to connect your SMTP and IMAP to MailReach and let it do the job the best way.
How to check SMTP reputation ?
But, according to us, as SMTP reputation is linked to email deliverability, we find it more useful to focus on checking your SMTP deliverability directly.
MailReach is a great tool to check your SMTP deliverability. MailReach gives you access to a powerful email deliverability checker both by using the SMTP warm up service and the spam testing feature.
When using the SMTP warmer, you can follow on your dashboard where your warming emails land and filter by email provider.
On top on that, our spam testing feature allows you to send your email to dozens of inboxes on the most important email providers and have an accurate view on where you land. MailReach gives you a Spam Score and helpful insights to improve it.
