@Aspreys - Rhiannon
I'm going to flag this post for the Zapier Community Team. They should have more insight on this and can escalate to the support team if needed.
Sit tight, and someone will contact you soon.
Hi @Aspreys - Rhiannon, I’m sorry that you’re having trouble adding your Exclaimer signature when emails are being sent using Zapier. It’s trick to tell if this is something that’s happening because of the way that Exclaimer adds the signatures, or because of a couple of known issues around using signatures with Gmail in Zaps right now.
I’m going to pass your message on to the Support Team so that someone can take a closer look at your Zap with you. One of the team will be in touch via email as soon as possible. Thanks!
