Mailfomo
Hey HN! We built MailFomo to help email marketers create urgency and drive conversions. The idea is simple: drop a live countdown timer into any email — it updates every time someone opens it. Works with any email platform like Mailchimp, Klaviyo, SendGrid, etc. It also includes AI tools to help you plan campaigns and create timers faster, plus ready-made templates so you can get started in seconds. Free tier available — would love your feedback!
Mailfomo launched on March 3, 2026 with 4 votes, #2,516 of 23,380 launches that month and more than 75% of that year's launches.
What it does
Mailfomo adds live countdown timers to your emails. The timer regenerates on every open, showing real remaining time — not a static image. Pick a template or let AI create one. Customize colors and fonts. Copy the embed code. Paste into Mailchimp, Klaviyo, SendGrid, Shopify, WooCommerce — anything that supports images. We also built in an AI campaign planner, impression tracking, and a template library. Free tier available. No credit card needed.
