🚀 Convex fam: We built Transmit on Convex—now soft-launching the unified comms API
Hey all! At Transmit, we're Convex die-hards: our entire backend—queues, retries, analytics—runs on Convex queries and actions for that buttery scalability.
Truth: We soft-launched transmit.dev to make adding production email (and beyond—like SMS/voice/chat in Q1-Q2 2026) as seamless as your Convex setup.
Send transactional emails from a single action, with webhooks that you can pipe right into your Convex DB. Uptime? 99.9%. Deliverability? We got you.
We're in private beta and would be honored to have our fellow Convex devs try it out.
It's free to sign up and comes with 3,000 free credits (3,000 emails) to get you started—no CC needed. Sign up here -> https://www.transmit.dev
We'd love to hear what you think!

Nice- The world needs more twilio alternatives!
agreed! we are close to launching the sms side. we are in private beta and working through the legalities of it all.
Heck, yeah, I’m so excited to see easy drop in stuff like this, and also really cool to see that you guys built this on convex. I just found it recently and I’m looking to adopt it for everything.
even though we just launched. we are working on a facelift for the marketing site.

@puchesjr It looks nice and modern, dev appropriate. May I give feedback? I think you should call out specifically what the platform does a little stronger. “Communications Infrastructure” isn’t quite clear enough. I would make clear mention of Transactional Email/SMS/Voice as your strongest cta, and have that big headline be more secondary. Or at least make that top callout a little stronger and more clear.
I ran a software and marketing company for a decade, and if there’s one thing I’ve learned, you have like 3 to 5 seconds to clearly tell people what you do, or your bounce rate is a lot higher.
I’m excited to try it out. I’m burnt out from all the time it takes to set up projects and integrate things that have nothing to do with the project lol. That’s why I’m moving to convex.
Let me know when you signup and if you have any questions/feedback/ problems
@zlanich

Much more clear!
nice... getting that yc aura without being in yc
thanks... hopefully y'all enjoy the design. convex has been fantastic to work with. will be sharing some videos soon.
