Transactional Emails Going to Spam from Lovable App
Emails sent by your Lovable app (welcome emails, password resets, notifications, receipts) are landing in users' spam or junk folders instead of their inbox. Some users never receive the emails at all.
Poor email deliverability means users miss critical communications — they can't reset passwords, don't receive order confirmations, and miss important notifications. This directly impacts user trust and business operations.
The problem may be inconsistent: emails reach Gmail but not Outlook, or they work for some users but not others. Corporate email addresses often have stricter spam filters that block your emails entirely.
Error Messages You Might See
Common Causes
- No SPF/DKIM/DMARC records — Your domain lacks email authentication DNS records, making spam filters suspicious
- Sending from a free email domain — Using @gmail.com or @outlook.com as the from address instead of your own domain
- New domain without reputation — Your domain is new and hasn't established a sending reputation
- Spam trigger words — Email subject or body contains words that trigger spam filters (FREE, URGENT, ACT NOW)
- No unsubscribe link — Marketing emails without an unsubscribe option are flagged as spam
How to Fix It
- Set up SPF, DKIM, and DMARC — Configure these DNS records for your domain in your DNS provider (instructions vary by email service)
- Use a dedicated sending domain — Send from an address on your own domain (e.g., noreply@yourapp.com) not a free email
- Use a reputable email service — Use Resend, SendGrid, or Postmark instead of sending directly from your server
- Warm up your domain — Start by sending small volumes and gradually increase to build reputation
- Check with mail-tester.com — Send a test email to mail-tester.com to get a deliverability score and specific improvement suggestions

Get HelpFrequently Asked Questions
What are SPF, DKIM, and DMARC?
These are DNS records that prove you're authorized to send email from your domain. SPF lists allowed sending servers, DKIM adds a cryptographic signature, and DMARC tells receiving servers what to do if checks fail.
Which email service should I use?
Resend is great for developers and integrates easily with modern apps. SendGrid and Postmark are also excellent. All three have free tiers for small volumes.
