Flap · useflap.online
JustEmails alternative for serial launchers
In short: JustEmails is a simple hosted email option some founders consider for a flat yearly fee. Flap (useflap.online) is built for people who keep launching domains and want one inbox, clear plan limits, and SES-backed send/receive.
If JustEmails’ flat-year model fits a single quiet brand, keep it. If you outgrow one mailbox story and need domain-first pricing plus developer hooks, Flap is the honest comparison.
Where Flap differs
Domain-first plans (Free 2 domains, Solo 5 at $7/mo, Builder 20 at $19/mo). Filters, aliases, JSON/.mbox export, API keys and inbound webhooks on Solo+, Studio seats for small teams.
Architecture
Customer mail on Amazon SES. App on Cloudflare. Your DNS stays at any registrar. You stay at your registrar; Flap does not force Cloudflare Email Routing.
Honest tradeoffs
JustEmails may win on ultra-simple yearly sticker for a minimal mailbox. Flap does not claim IMAP/SMTP yet and is not a productivity suite. Prefer Flap when multi-domain inbox + transparent quotas matter.
FAQ
Is Flap cheaper than JustEmails?
Depends on domain count and whether you need send quotas, filters, and team seats. Compare live pricing at /pricing rather than a single yearly headline.
Can I migrate automatically?
Not yet. Point DNS, recreate addresses, and import older mail manually if needed. Export from Flap anytime.
