Letterkit
AI Builds your Marketing Emails, sequences and replies!
Most founders struggle to finish marketing email. Letterkit learns your brand from your site, writes emails and the sequence, writes back on replies, and grows your list with a widget or forms. Free to start — no card, unlimited subscribers.
Hey Product Hunt! 👋 Sammy here.
I got tired of watching founders (and myself) know they needed marketing email—welcoming users, following up, answering replies, and growing the list—only to stall on a blank campaign or give up on a tool that takes weeks to set up.
Why existing tools fall short:
Big platforms (Klaviyo, Mailchimp): Powerful, but bloated and complex for fast-moving founders.
AI Copywriters: Give you static text, but leave you to build the workflows, handle customer replies, and set up capture forms manually.
How Letterkit fixes this:
🧠 Learns your brand automatically: Scrapes your site to capture your voice, value props, and positioning.
⚡ Writes full email sequences: Generates converting welcome and nurture campaigns that run on autopilot.
💬 Handles inbox replies: Automatically drafts smart replies so conversations don't die in the inbox.
📈 Built-in list growth: Includes a subscribe widget, customizable forms, and shareable landing pages.
Product Hunt Launch Deal:
Start 100% free—no credit card required and no per-subscriber tax.
I’d love your feedback:
If you run a SaaS, brand, or side project, what’s the #1 reason email marketing isn't live for you yet—is it writing copy, setting up sequences, handling replies, or lead capture?
Give it a spin at Letterkit.co and let me know what you think! 🚀
