How to filter and hide MailReach emails in your inbox [Gmail / Office 365]
If you send campaigns from secondary mailboxes and redirect the replies to your customers' (or sales reps), we have a dedicated guide to help you prevent warming emails to be forwarded to their inbox (Gmail).
TL;DR
- By default, MailReach's warming emails are hidden from your mailbox and stored in a folder named "To Follow", but it can't be 100% reliable (that's normal) and it can take some time.
- In this guide, you'll be guided to set up a filter to hide the emails and redirect them without any delay and with more reliability.
- It should take you 3 minutes.
Step 1 : copy your filter code
- In your MailReach account, in the Top Bar, click on Email Warmer
- Find the mailbox you'd like to set up the filter and click on Show
- Click on your Filter Code to copy it

Step 2 : create the filter to hide the emails and redirect them

- Check "Skip the Inbox (Archive it)"
- Click on "Apply the label" and select "To Follow"
- Click on Create filter. You're done 🎉
For Microsoft / Outlook / Office 365
