FAQ
What is email warmup and how does it work?
Email warmup is creating activity on your email accounts. After you connect your email account, we are going to start email communication between users in our private pool. We also going to read and reply to those emails to emulate human-like activity.
How it increases my deliverability?
When mail servers receive an email, they analyze many different parameters to classify it as spam. The reputation of the email is one of the key factors. With email warming, your mailbox will interact with others, and mail servers will see that your messages are interesting to recipients, thereby increasing the reputation of your email.
Do I need to warmup only new accounts?
No, we recommend keeping the warming on all the time. Firstly, your server will see that you are frequently sending emails, which will increase your limits. Plus, warming is a kind of "treatment" for the mailbox; if a certain mailing has lowered the reputation of the mailbox, warming will gradually restore it over time.
How Warmup emails will look like?
It's very important to make sure that each sent email will be recognised as "Unique" and "Human-like" by your email provider. To make sure all of your emails are unique, we've created thousands of different variations of each part of your warmup email. Every time we send Warmup email, we combining different variations together "Lego" construction, which results in over a billion unique emails.
Here is the example of one of them:
