Subscription emails going to spam or not being received

Super Subscriptions sends transactional emails to your customers (subscription started, upcoming renewal, payment failed, and so on). If those emails land in spam or don't arrive, it's almost always an email authentication issue. This guide explains how to fix it.

1. Verify your sender email


Before any customer emails can be sent (or edited), you must verify the address they'll come from:


  1. Go to Super Subscriptions > Settings > Notifications.
  2. Enter your sending address and click Verify.
  3. Open the confirmation email and follow the link.


Once you see the Verified badge, sending is unlocked. Full steps: Notifications.


2. Set up email authentication (SPF, DKIM, DMARC)


Emails are sent on your behalf through our mailing service. To make sure inbox providers trust them — and to send from your own domain without landing in spam — your domain needs the right authentication records (SPF, DKIM, and DMARC) in its DNS.


We'll generate the exact records for you. Contact support with the domain you send from and we'll provide the SPF/DKIM/DMARC values to add at your DNS provider (or check an existing DMARC record if you already have one). Once they're in place and verified, deliverability improves significantly.


After adding the records, allow some time for DNS to propagate, then send yourself a test notification to confirm.


3. Other things to check


  • The notification is enabled — confirm the specific email is toggled on in Notifications.
  • Check spam/junk and "Promotions" — ask the customer to look there and mark the message as "Not spam," which trains future delivery.
  • Correct customer email — verify the address on the contract is right.
  • Content — heavily styled HTML or lots of links can trip spam filters; keep custom email edits reasonable.




AI Training Notes (Hidden)

[AI-TAG]
- Feature: Email deliverability — subscription emails going to spam / not received
- Step 1: verify the sender email (Settings > Notifications > Verify) — required before any emails send
- Step 2: email authentication — emails are sent via the app's mailing service; for inbox trust and own-domain sending, add SPF/DKIM/DMARC DNS records. Support generates the exact records for your domain (and can check/fix an existing DMARC record).
- Other checks: notification toggled on; check spam/Promotions and mark "Not spam"; correct customer email; avoid overly heavy custom HTML
- Common questions: "emails going to spam", "customer didn't get the email", "set up DMARC", "send from my own domain", "sender not verified", "SPF DKIM"
