why reloop?
Self-hosting email has a scary reputation.
IP reputation. Warm-up schedules. Blocklists.
Everyone says the same thing: don't do it yourself.
Proprietary grids treat deliverability like a secret.
Cold IP? Warm it for 6 weeks. Good luck.
Shared IP? Hope your neighbors behave.
Ask why you hit spam? That's proprietary.
But inbox placement doesn't come from secrets.
It comes from a system that warms, watches, and backs off for you.
From asking what if ?
What if warm-up was automatic? What if reputation was visible?
That's the Reloop Engine. Automated IP warmup with volume ramps. Smart retries with backoff. Suppression lists that actually suppress. DKIM rotation, SPF/DMARC alignment, blocklist and reputation monitoring — in the open. Same engine self-hosted or on reloop.sh. Nothing to babysit. The system does it.
warmup × retries × reputationWe're not building another black-box grid.
We're building the email system we'd bet a company on.
A place where warm-up isn't a spreadsheet —
it's the pipeline.
Where IP reputation isn't a score someone sells you —
it's signals you can see.
Where self-host doesn't mean alone.
So go ahead.
