Hi everyone!

In Sequences, I have a challenge:

Is there a way to “block/suppress” contacts, from receiving the one-to-one emails in sequences, based on the email domain?

As a workaround, I thought I could do this:

- Create suppression list \> Filter: specific client email domains
- \> Filter: Opt-out from one to one emails
- Create workflow \> Trigger: List membership \> Suppression list
- \> Action: Set contact property \> Opt-out from one to one emails
- \> Action: Set company property \> Opt-out from one to one emails

Can anyone please give me advice - will this work? Or are there any other workarounds that would be better suited for this issue?

I would REALLY appreciate anyone’s help with this!

Hi @johanwaldeck,

Opting them out from the one-to-one email subscription type would indeed be the safest option. You could simplify it however:

 ![](https://d2qpr2jzcazej7.cloudfront.net/original/3X/d/c/dc268591953fb567508ea0f1e56b34f8e6ce4422.png)

The enrollment criteria check whether a contact does have a certain email domain (this could also be referenced via a list, yes) and whether the contact is either opted in or does not have an opt-status (because why enroll contact that are already opted out).

Recently, a feature was added in workflows that lets you unenroll contacts from a contact-based workflow – but that is useless here as a contact would have to be enrolled to begin with.

Hope this helps!
