No password · Cancel anytime · Beta pricing locked
Built for one job. Done well.
No inbox to manage. No team. No threads. Mailer sends a single message — to you.
Email reminders
Drop it in your personal or work inbox. Delivered via Resend, indistinguishable from any other email you'd actually read.
WhatsApp drop
Send a reminder straight to your WhatsApp. Read it on your phone — before everything else fights for your attention.
Send later
Schedule a delivery for tomorrow morning, next Monday, or that meeting you keep forgetting to prep for.
Three steps. That's it.
- 01
Sign in
No password. Google or a one-time email link. Done in five seconds.
- 02
Set your destinations
Personal email, work email, WhatsApp number. Configure once, forget.
- 03
Send to yourself
Type. Pick a channel. Send. Read it where you live, not in another notes app.
Your agent can remind you, too.
Mailer ships an MCP server. Point Claude Code — or any MCP client — at it, and your agent can send you a reminder in the middle of whatever it's doing.
- Two tools, nothing elsesend_email (personal or work, now or scheduled) and send_whatsapp (immediate).
- It can only write to youBoth tools deliver to the destinations you set in /settings — never to an arbitrary recipient.
- Your own keyGenerate one in /settings. It's shown once, and it's the only credential the server accepts.

Frequently asked.
What is Mailer?
Mailer is a one-purpose tool: send a message to yourself, by email or WhatsApp, in one click. Think of it as a journaling shortcut that lands somewhere you'll actually re-read it.
Why pay for self-reminders?
Mailer pays for delivery infrastructure (Resend, WhatsApp), keeps your data private, and ships fast. If your time is worth more than ten minutes a month, Mailer pays for itself.
What happens when Beta ends?
Pricing will go up. Existing Beta subscribers keep their $10/mo plan as long as the subscription stays active. New users will pay the GA price.
Can I cancel anytime?
Yes. Subscriptions are billed monthly via Polar. Cancel from your billing portal — no questions, no calls, no retention emails.
Stop forgetting. Start mailing.
