Build a reliable transactional program with authentication, list hygiene, and monitoring habits that protect inbox placement.
Transactional messages are expected — password resets, receipts, security alerts. Recipients did not opt into a newsletter; they triggered the send. That means providers judge you on speed, relevance, and complaint rates rather than campaign engagement.
Configure SPF and DKIM before production traffic. Authentication gives mailbox providers a verifiable signal that you control the domain you send from.
Add your domain in the Mailsurge dashboard, publish the DNS records, and wait for verification before your first live send.
Remove invalid recipients quickly, never purchase lists, and suppress addresses that hard bounce or mark mail as spam.
Treat every complaint as an incident. Trace the triggering event, fix the product flow, and add the address to a global suppression list.
Match subject lines to message intent, avoid deceptive wording, and include a plain-text part alongside HTML.
Receipts should look like receipts. Security alerts should name the product and action clearly — not generic “Important update” subjects.
Keep critical emails on a dedicated stream so promotional campaigns cannot damage their reputation or throughput.
Many teams use mail.yourproduct.com for transactional mail and separate keys for lifecycle or newsletter sends.
Process delivery, bounce, and complaint events in near real-time so bad addresses are suppressed before the next send.
Make handlers idempotent — providers retry webhooks. Store event IDs or use upserts to avoid double-processing.
Track send volume, bounce percentage, complaint percentage, and queue latency. Small regressions caught early are easier to fix than full deliverability incidents.
Review metrics after every major launch, pricing change, or onboarding flow update that increases send volume.
