Custom Email Domain

By default, outbound emails (sent via /send) come from no-reply@mail.scitor.io. This guide shows how to set up your own sender address so replies come from your company’s email domain.

Prerequisites

• A domain you own (e.g., yourcompany.com)
• Access to your domain’s DNS settings
• Scitor installed on your repository

Step 1: Verify your domain

Before you can send from a custom address, the domain needs to be verified with the email sending provider. Contact Scitor support or verify through the Resend dashboard to add your domain’s SPF and DKIM records.

Required DNS records (example):

Type    Name                            Value
TXT     _dmarc.yourcompany.com          v=DMARC1; p=none
TXT     yourcompany.com                 v=spf1 include:send.resend.com ~all
CNAME   resend._domainkey.yourcompany.com   [provided by verification]

Step 2: Set your sender address

Once the domain is verified, use the /set-from-address command:

/set-from-address support@yourcompany.com "Acme Support"

This sets:

• From email: support@yourcompany.com
• From name: Acme Support

Step 3: Test it

Send a test reply using /send and check that the email arrives from your custom address.

Resetting to default

To revert to the default Scitor sender address:

/set-from-address no-reply@mail.scitor.io "Scitor"

Why verify?

Email authentication (SPF, DKIM, DMARC) ensures:

• Your emails are delivered (not flagged as spam)
• Recipients see your company name (not Scitor)
• Email clients show a verified sender badge
• Compliance with email provider policies
