FAQ: Can I warm up my inboxes in QuickMail?
For Google compliance, we stopped our auto-warmer feature entirely.
To replace it, we created an integration with a different auto-warmer tool called MailFlow. (It's safe and free)
New Mailflow accounts will be on a 14-day trial.
Before the trial ends, the Mailflow account must be subscribed to the Free plan (reduced the daily auto-warmer limit of each inbox to 5). Otherwise, it will stop email warming.
If you decide to go on a paid subscription with QuickMail, MailFlow can increase your daily auto-warmer limit to 30 per day per inbox. Just contact their support at firstname.lastname@example.org.
Here is a breakdown from MailFlow of the steps to get started: Quick Setup Guide
