How does Mailgo Warm-up Work?

What is Email Warm-up?

Email warm-up is a process designed to prepare email accounts for marketing campaigns. Mailgo’s warm-up service simulates real email interactions—such as sending, receiving, and replying—to improve the sender reputation and ensure emails land in the recipient's inbox instead of the spam folder.

This may sound complex, but don’t worry—Mailgo handles everything automatically. With this hands-off solution, your campaigns can reach more cold leads, generate better engagement, and achieve greater results.

Let's see: What happens after connecting account to Mailgo

How to Enable Email Warm-up?

When you add a new email account, Mailgo will automatically start the email warm-up process. On the Accounts page, you can view the warm-up status of your email accounts, such as Active or Paused, along with your current reputation score and other warm-up details. You can also use the control button at the end of the row to pause or restart the warm-up process at any time.

Warm-up Panel and Reputation Score

By clicking on an account, you will access the account management panel, where the first tab is the Warm-Up panel. In this panel, you can view the current reputation score, the destination of warm-up emails that have sent, and warm-up activity statistics of the account.

The reputation score reflects the overall health of your email account. The higher the score, the greater the likelihood that your marketing emails will land in the recipient's inbox. Accounts are categorized into three statuses based on their reputation score.

Mailgo recommends starting your marketing campaigns when the score is 100. However, you can design your activities based on your reputation status as appropriate, but please keep this in mind: sending marketing emails when your reputation score is low may further decrease the score.

💡Best pratices:

Generally, a new account needs to be warmed up for 14 days, and the score will reach above 80. (See more -->What happens after connecting account to mailgo)

However, it should be noted that if too many emails are complained about and the account is identified as a spam mailbox by the service provider, it is difficult to improve the overall score through warm-up.
