Make app emails actually arrive - shippingszn launch readiness
When your app sends emails (welcome, password reset, receipts, invites), they need to land in real inboxes from a real sending domain. A dedicated email service plus SPF, DKIM, and DMARC is what keeps your app from looking broken when the code technically sent the message.
Email bugs feel like product bugs to users. If password reset, login code, receipt, or invite emails land in spam, people do not think 'deliverability issue' — they think your app does not work. This is also where paid users get locked out and refund requests start.
Owner verification required: Email deliverability lives in provider dashboards and real inboxes. The scanner cannot prove SPF, DKIM, DMARC, templates, retries, or inbox placement without a delivered test email.
The Launch Fix Kit keeps scan-specific findings, file and line evidence, AI-builder punch-list tasks, and verification steps tied to the paid report.
- Pick a provider: Resend (modern, dev-friendly, generous free tier) or Postmark (excellent deliverability) for transactional. SendGrid if you need bulk.
- Create an account and verify your sending domain. Add SPF, DKIM, and DMARC DNS records, then wait until the provider marks them verified.
- Replace anywhere in your code that sends email to use the provider's SDK. Ask your AI builder: "switch all my outgoing email to use Resend."
- Build clean templates for: welcome, password reset, key transactional events. Keep them simple and on-brand.
- Test every critical flow by sending to your own Gmail, iCloud, and Outlook/Hotmail addresses if you can: signup, password reset, login code, invite, receipt, and support reply.
