Helpdesk: Allow custom sender email domain for ticket replies (instead of success-mail.com)

Hi Klaviyo team and community,

Currently, when replying to email tickets in Klaviyo Helpdesk, all outbound emails are sent from the Klaviyo workspace address (e.g., support-mybrand@success-mail.com).

This is problematic for several reasons:

  1. Trust & Professionalism: Customers receive support emails from an unfamiliar domain (success-mail.com) instead of our brand domain. This looks unprofessional and can appear like phishing or spam.
  1. Brand Consistency: Our marketing emails come from our own domain, but support replies come from a completely different domain. This creates confusion for customers.
  1. Deliverability Risk: Generic domains like success-mail.com may have a higher chance of landing in spam folders compared to established branded domains.
  1. Customer Confusion: When customers reply, they might reply to the wrong address or be confused about who they're communicating with.

Feature Request:
Please allow us to configure a custom sender email address/domain for Helpdesk ticket replies, similar to how we can set up a branded sending domain for marketing emails.

Is this feature on the roadmap? Are there any workarounds available?

Thank you!

Hey ​@Marvin,

You raise some really good points, and I recognize that not being able to customize the domain that your Helpdesk emails come from isn’t ideal. I’ll speak to our team that handles Helpdesk and recommend that we customizable email addresses in Helpdesk to our roadmap in the future! Thanks for the thoughtful feedback.
