Custom Email Domain Setup 

Last updated: April 16, 2026

About this feature

By default, all invoice and payment reminder emails sent from Tabs come from a Tabs email (no-reply@tabsapp.com).

With Custom Email Domain enabled, Tabs can send invoices using your company’s email address, such as:

Your customers will see your email instead of a Tabs email.
Any replies (questions, disputes, payment confirmations) will go directly to your inbox, not Tabs.

Setup Requirements 

This feature requires a one-time setup with your IT or DevOps team to authorize Tabs to send emails on your behalf. Please reach out to your Implementation or Customer Success Manager to get started.

Step-by-Step Instructions 

Step 1: 

Provide setup details to Tabs


Share the following information with your Tabs Implementation or Customer Success Manager:

Step 2: 

Create or enable the email inbox

Make sure the email address provided above is setup properly and can receive replies.

If using Google Workspace

  1. Create a Google Group using the sender email address

  2. Allow external senders

  3. Add invoices@tabsplatform.com Tabs as a ‘group member’ subscribed to each email

  4. Add forwarding if multiple teammates need visibility

If using Outlook / Microsoft 365

  1. Create the mailbox or shared inbox

  2. Confirm external senders can reply to it

Step 3: 

Add DNS records

Tabs will send an automated email to your IT/DevOps contact with the necessary DNS records.

Your IT team will:

  • Add SPF / DKIM / CNAME entries to your domain DNS settings

  • Confirm once records are saved

You’ll receive an automated email asking you to verify the domain, click the confirmation button.

Step 4: Tabs activates your domain

After DNS is verified, Tabs will activate your custom domain on our side.

Once active:

  • All future outgoing emails (invoices, reminders) will come from your custom address

  • Customer replies will route back to your inbox

FAQs

Can we have multiple From: addresses?
Not yet.  At the moment, Tabs supports one sender domain per merchant.

Is this self-serve?
No. Tabs will need to activate and validate once DNS is set up.

Will this improve deliverability?
Yes. SPF/DKIM authentication improves inbox placement and reduces spam filtering.
