Key things to know
- Propilot domain works immediately with no DNS setup. Custom subdomain needs DNS records added and verified first.
- Your sender address locks permanently after the first email is sent. This protects existing conversation threads, so choose it carefully.
- The custom subdomain option stays disabled in the default sender choice until verification passes.
- Only admins can change Email Setup. Click Save email settings to apply changes.
Where to find it
Open Settings from the sidebar, then choose Email Setup under Basic Setup. The section is titled Email Domain.What you configure
Which option should I use?
You can configure both and switch the default between them at any time. Replies route into
ProPilot either way.
Set up a custom subdomain
1
Enter your domain
On the Custom subdomain tab, fill in Domain you own (for example acme.com) and
Subdomain (for example inbox). ProPilot shows the proposed hostname, such as
inbox.acme.com.
2
Add the DNS records
ProPilot lists the exact records to add, including MX records, with Type, Host, Value, and
Priority. It also detects which DNS provider manages your domain and shows provider-specific
tips, such as whether to enter the host relative to your zone or as the full record name.
3
Verify
Save the records at your provider, then click Verify DNS. Changes usually propagate
within minutes (typically 5-30) but can take up to 48 hours. The tab shows a Pending
badge until checks pass, then Verified.
4
Set it as the default sender
Once verified, the Custom subdomain option unlocks under Default sender domain.
Select it and click Save email settings.
The sender address lock
The Sender Email field (the part before the @) can be edited until your organization sends its first email. After that, it locks permanently and shows a Locked badge. This prevents broken email threads and missed replies that would happen if the address changed mid-conversation. If you genuinely need to change a locked address, contact support, and note that changing it may break threading on existing conversations.What this affects
- All outbound email - Messages, Bulk Messaging, and email steps in Sequences send from the current default sender.
- Replies - agents reply to your sender address and those replies appear inside ProPilot.
- Templates - Message Templates keep their content; only the sending address changes.
- Trust and deliverability - a verified custom subdomain shows agents an address on your own brand.
Limitations
- The sender address locks after the first sent email and can only be changed through support.
- The custom subdomain cannot become the default sender until DNS verification passes.
- Only organization admins and owners can change these settings.
- Email signature, email forwarding, CC/BCC defaults, and reply mirroring are configured separately under Advanced Settings > Communication. The page links there via Open Email Forwarding.
Common questions
Why is the Custom subdomain option greyed out?
Why is the Custom subdomain option greyed out?
It unlocks only after you complete DNS setup and verification on the Custom subdomain
tab. Until the status shows Verified, the default sender stays on the Propilot domain.
Why is my custom domain still not verified?
Why is my custom domain still not verified?
Check that every listed record was copied exactly, including Type, Host, Value, and Priority,
and watch the provider-specific host tip: some providers want the host relative to your zone
rather than the full hostname. Then allow time for DNS propagation - usually minutes, up to
48 hours - and click Verify DNS again.
Can I change my sender address?
Can I change my sender address?
Yes, until your first email is sent. After that it locks permanently to protect existing
threads. Contact support if you must change a locked address.
Do replies go to my regular inbox?
Do replies go to my regular inbox?
Replies arrive inside ProPilot. If you also want copies in an external mailbox, set up email
forwarding under Advanced Settings > Communication.
If I switch sender domains, what happens to old conversations?
If I switch sender domains, what happens to old conversations?
Existing sent messages keep the address they were sent from. New sends use the current
default sender domain. You can switch between configured options at any time.
