Tilta can send buyer-facing emails from your own domain, so every communication your buyers receive appears to come directly from your platform rather than from a generic Tilta address. You have two options: delegating a subdomain entirely to Tilta (the simpler path), or configuring Tilta to send from an address on your main domain (which requires additional routing setup). Both options use the same DNS-based authentication infrastructure.

​
Sending from a Subdomain

Delegating a dedicated subdomain to Tilta is the recommended approach. It requires no changes to your main domain’s DNS records or email routing, which avoids any risk of disrupting existing email flows. Tilta handles all sending, bounces, and link tracking through the subdomain you assign.

​
Choose Your Subdomain

Pick a new, unused subdomain that has never been used for email before. Using an existing subdomain that already has MX records or SPF policies can cause delivery conflicts. Good options include:
  • accounts.your-domain.com
  • invoicing.your-domain.com
  • billing.your-domain.com
  • pay.your-domain.com
Do not reuse a subdomain that already handles email or has existing MX records. Create a brand-new subdomain specifically for Tilta. If you have any doubt, check with your DNS administrator before proceeding.

​
DNS Records

Add the following DNS records for your chosen subdomain (replace subdomain with your chosen name and your-domain.com with your actual domain):
The MX record for your subdomain routes any inbound replies to Tilta’s infrastructure, which handles them appropriately (for example, processing out-of-office replies to suppress notifications). This record does not affect email delivery on your main domain.

​
Setup Steps

1

Choose and reserve your subdomain

Decide on a subdomain name (e.g., invoicing) and confirm it is unused – no existing MX records, A records pointing to an email server, or prior SPF entries. Reserve it in your DNS zone by noting the full subdomain: invoicing.your-domain.com.
2

Add the required DNS records

Log in to your DNS provider and add all four required records from the table above. Use your chosen subdomain name in place of subdomain. DNS propagation typically takes between a few minutes and 48 hours depending on your provider and TTL settings.
3

Add the DMARC record (recommended)

Add the TXT record for _dmarc.subdomain with the DMARC policy shown in the table. Using p=none starts in monitor mode, letting you review DMARC reports without rejecting any mail – upgrade to p=quarantine or p=reject after confirming legitimate mail is authenticating correctly.
4

Provide your subdomain to Tilta

Share the full subdomain (e.g., invoicing.your-domain.com) with your Tilta integration manager. Tilta verifies the DNS records and activates sending from your subdomain. You will receive confirmation once the domain is live.

​
SPF Alignment Note

Strict SPF alignment (aspf=s in your DMARC policy) is not supported for subdomain configurations. Use relaxed alignment (aspf=r, which is the DMARC default) to ensure emails pass authentication checks.

​
Verifying your setup

After completing your chosen configuration and notifying your Tilta integration manager, Tilta performs DNS verification before activating your custom sender. To avoid delays:
  • Confirm all required DNS records are published and resolving correctly (use a tool like dig or an online DNS checker)
  • Allow up to 48 hours for DNS propagation if you have recently made changes
  • Test your email redirection (for the main domain option) before submitting to Tilta for verification
You can use the sandbox environment (https://api.tilta-sandbox.io) to trigger buyer email flows and verify that emails are sent from your configured address before going live in production.

​
Frequently asked questions

Yes – the MX record on your subdomain handles inbound routing (for replies and bounce handling), while the CNAME records handle outbound authentication (DKIM, bounce domain, tracking). All four required records work together on the same subdomain.
Tilta falls back to a Tilta-hosted domain for sending. Emails will still display your platform’s name and logo in the body, but the sender address and domain will be Tilta’s rather than yours. For the best buyer experience and deliverability, configuring a custom sender domain is strongly recommended.
Tilta’s sending infrastructure sends on behalf of your domain using its own mail servers. Strict SPF alignment (aspf=s) requires the From header domain to exactly match the envelope sender domain, which is not compatible with this architecture. Relaxed alignment (aspf=r), which is the DMARC default, allows the subdomain or sending domain relationship and works correctly with Tilta’s setup.
Once you have added all DNS records and notified your Tilta integration manager, verification typically completes within one business day – assuming DNS has fully propagated. Complex DNS setups or propagation delays may extend this timeline.
