Is anyone else having issues with campaign emails just completely vanishing? I’ve had several loyal customers tell me they aren't getting our emails at all. and when they search their entire account (Spam, Trash, Promotions, everywhere), the email is completely missing.

When I asked support about it, they told me I need to get my customers to manually whitelist "sendersrv.com" in their personal email settings. Honestly, that’s just not realistic or professional when you run a business.

I have looked up Google Postmaster Tools to see what was going on, and our domain score is sitting at a terrible 14% for SPF. I think this is happening because Sender forces all of our emails to use their background tracking domain (sendersrv.com) instead of our own business domain name. When Google or Yahoo see that mismatch, they flag it as suspicious and silently delete the email before it even hits the customer's spam folder.

Sender really needs to add a option for a Custom Bounce Domain (or Custom Return-Path). Pretty much all competitors like MailerLite and Brevo let you do this for free. It just lets you link your own domain in the background so Google trusts you and actually delivers the mail.

Please upvote this so the dev team can fix this infrastructure issue. It's hurting all of our delivery rates.
