Warmup filters help prevent warmup emails from appearing in your master inbox.
To set them up, go to the Master Inbox page from the top navigation bar of your Maildoso dashboard. On that page, click Set Up Warmup Filters near the bottom. Then select your sending tool and enter the appropriate warmup tag.
If your tool is not listed, choose Custom and manually add the relevant tag.
Tip: if warmup emails still slip through, it's usually a tag mismatch. Use a single, consistent warmup tag — set one warmup tag in your sequencer (via its Bulk Actions), then mirror that exact tag here under Set Up Warmup Filters → Custom.
Please note, this works for the @maildoso.email Master Inbox (SMTP) only.
