Magic-link auth emails that land in Gmail primary. Usage alerts that reach the admin before a bill spike. Invoice reminders that recover 40-60% of failed annual renewals. In-app push that respects OS-level throttling. Incident status pages that fan out to email + push + SMS + Slack. Built by a team running 6+ SaaS products of its own.
Every SaaS ships email in a hurry. First it is SendGrid free tier for signup emails. Then Postmark for transactional. Then a marketing team lands and pipes broadcast through the same domain. Six months later the sender reputation is trashed, magic-link emails land in Gmail promotions, and a support engineer is spending Friday evenings resending confirmation codes from an admin panel.
Dunning is the second silent tax. Every annual card renewal has a 12-18 percent first-attempt failure rate. Most SaaS wire a Stripe smart-retry and stop. The recoverable percentage sits at 15-25 without a proper email + in-app + CS handoff sequence. A tuned dunning flow gets that to 45-65 percent recovery. On $2M ARR that is $80-120k of net-new revenue that was already earned and is being left on the table.
Then product notifications. Slack-style mention emails, someone-shared-a-doc emails, weekly digests. Teams ship each one as a one-off. There is no central preferences layer. Users get 8 emails an hour and eventually filter the entire domain to trash. Later, when a real security alert or billing failure needs their attention, the email lands in the same muted folder. Fixing this requires an event router, not another feature.

Since February 2024, Gmail and Yahoo enforce hard rules on bulk senders. If you send more than 5,000 emails a day to Gmail addresses you need SPF, DKIM, DMARC alignment, a one-click unsubscribe header on marketing, spam complaint rate under 0.3 percent, and no phishing-like link patterns. Fall out of compliance and Google bounces the whole domain. We set up all six requirements at go-live and monitor complaint rates weekly.
GDPR obligations: legal basis for each message type (contract for transactional, legitimate interest for product updates, consent for marketing), DPAs with vendors, right-to-erasure across message logs. Postmark, SES and SendGrid all have DPAs we know how to sign. DPDP (India): consent capture at signup, purpose limitation, breach notification wiring, opt-out synced across email + push + SMS.
SOC 2 auditors want message audit trails. Every send logged with recipient, template, timestamp, provider, delivery outcome, opens and clicks (where applicable). Retention configurable per message type. We ship the audit query interface so your compliance team stops emailing engineering every quarter for reports.
