Re: not added to subject, when using Gmail Reply action with HTML body

When using a Zap to automatically send a reminder to an email in Gmail, I would like to make visible in the subject that it’s a reply (Re:). This works when I choose plain body text, but doesn’t work when I choose for HTML body. How can I solve this?

The Zap is triggered by a change in Airtable, then searches for the old email in my sent items in Gmail, and then sends a reply to that message with Gmail. I use the ‘thread ID’ from the search step to make sure the action step is a reply to that particular message.

Hey folks, just stopping by here to share that the feature request has now been implemented! 🎉

In case you missed the email notification that went out here’s what you need to know:

We’ve added a new feature that allows you to edit the subject line when using the Reply to Email Action, including the ability to add “Re:” for more traditional email threading. The original email’s body content is also preserved in your replies.
There’s nothing you need to do—this feature is available for you to use right away when setting up or editing your Zaps.

Thanks so much for everyone’s patience on this long-standing feature request—we’re excited for you to give it a try! And if you run into any issues with it, feel free to start a new topic or reach out to our Support team directly and we’ll be happy to assist.

In the meantime, happy Zapping! ⚡

Hi @Harold 

Good question.

Try using this Zap action: Gmail - Send Email

You can configure a custom Subject.

 

Otherwise, you may want to open a ticket with Zapier Support for further guidance: https://zapier.com/app/get-help

Hi there @Harold - thank you for coming into the Community with this question. 

 

Troy is correct, in the Send Email option you are able to configure a custom subject. That option is not currently available in the “Reply to” email action. 

 

I’ve added you to the current lists of folks requesting this feature. I don’t have an ETA of when or if this will happen, but we will definitely email you if it does become a reality.

I do not think that is a good solution as in the background the reply is not in a thread and is then recognized as an answer to that email.

Either add the “Re:” automatically to the reply or let user decide, but that one is definitely not a solution.
