Best of the inbox: a bounce-handling workflow that protects you
Ignoring bounces is how good senders get blocklisted. This is the processing logic to copy.

🔧 Classify
— Split hard vs soft, automatically — hard bounce = suppress instantly and forever. No exceptions, no manual review.
— Parse the soft-bounce reason — full mailbox vs greylisting vs blocked are three different actions, not one.

⏳ Retry rules
— Soft-bounce: retry 2-3x over 72h, then suppress — endless retries to a dead box wreck your reputation.
— Treat 'blocked' soft bounces as a reputation alarm — that's a filter talking, investigate immediately.

📊 Watch
— Keep total bounce rate under 2% per send — above it, stop and clean before the next blast.

Why these made the cut: automatic classification and the suppress-forever rule are what keep one bad import from sinking you.
