I built a tool for devs who are tired of babysitting SMTP and deliverability every time they ship a new app or spin up a small SaaS: SMTP Zen.
It’s a transactional email + standard mailbox service aimed at developers, freelancers and domain investors who just want stuff to land in the inbox and move on with their lives.
What it does:
Unlimited domains & mailboxes – No “seats”. Add as many domains/mailboxes as you need and forget about artificial limits.
SMTP that actually lands – Guided SPF/DKIM/DMARC setup and enforced TLS so you don’t have to become an email wizard to stay out of spam.
Simple sending & forwarding – Custom domains, per-client aliases and mailbox-free forwarders. Great for spinning up project/client addresses in seconds.
Real-time logs – Full send/receive paths and errors for every message so debugging deliverability isn’t a guessing game.
Zero-downtime IMAP migration – IMAP sync with automatic delta sync, so you can move existing mailboxes without scary cutovers.
Usable webmail & dashboard – Fast webmail (Crossbox) with unified inbox, calendar and contacts, plus a clean panel for domains, DNS, mailboxes, forwarders, logs and billing.
As a launch promo I set up a 20% off coupon (valid until Dec 31):
