🎉 ColdSend v1.0 is now LIVE!
The wait is over! ColdSend v1.0 with all the features mentioned below is now available. Start sending today with automated domain setup, spintax support, agency features, and more.
The last announcement in our Discord server said that the new backend will be ready by the 20th (with a cheeky "tentative" in the parentheses, in our defense). It's the 22nd now and I'm sure (hope) everyone is waiting for an update.
TL;DR we dun goof'd hard and vibe coded the first backend which broke a lot of things and are 98% done with the new backend and currently in the testing phase.
The Backstory: How ColdSend Started
Once upon a time, I was trying to crack cold outreach for a $60/mo product. When I did the math, nearly all the existing solutions – Instantly.ai, Smartlead.ai, Lemlist, etc. – were in the ballpark of $1500/mo for "at-scale" (i.e., 10k) campaigns. The biggest expenditure was of course lead lists; 2nd biggest, infra; 3rd, sending.
That ticket size didn't make sense unless I could convert at least 25 people out of the 10k. Risky move. And that's not including the personnel cost of course (I mean, yes founders are unpaid but still).
Being engineers, we (as in, me and Hamza) decided to reverse-engineer Hypertide. How could they offer 8 inboxes for just $30/mo? Yes, there was a $1500 one-time setup fee which more or less offset the cost but surely, it was still a steal given the industry standard.
One late night at 2 AM while I was doomscrolling, Hamza texted me something like:
"Bro, I think we don't need warmups. I figured out a way".
And that was that. I didn't believe it at first but it was Hamza, and he usually has amazing revelations. Usually. So I told him to put it to the test.
He hacked together a really shitty MVP, entirely vibe coded that looked like this:

But ... it worked. We sent 1,000 emails in a couple days. Got 60%+ opens, 10%+ replies. Actual human replies. We continued testing. One time, the scheduler bugged out and sent the same email five times to everyone and people replied to it. Like, some variant of "fuck off". But the fact they replied meant the emails landed. In primary.
Customer complaint about duplicate emails
That was the validation we needed.
It was at this time that we decided to onboard Zeeshan as the 3rd co-founder. Zeeshan is the product design mastermind behind several $10M+ ARR products that you probably have never heard of unless you're a genAI degenerate – ok it's Imagine.art and Chatly. And several more.
The biggest problem with our vibe-coded MVP, or what we thought was the biggest problem, was ... the design. It sucked. And coming from almost a year of vibe coding microSaaS, I knew no amount of vibe coding can match an actually deliberately designed product.
My only request to Zeeshan: "Dude, please keep it simple". And he did. He designed the entire frontend within a week, then we hacked it together in a couple weeks and made it live ... on August 1st.
What Went Wrong
From this point on, you probably know the story. The product worked. But barely.
We knew things would break which is why we decided to offer a free trial to everybody in the beta. The problem was ... every fix made other things worse.
And the biggest problem was the scheduler, which at this point was very complicated (we tried building the world's first scheduler that can be paused at any time – and failed; but succeeded later on, hopefully). And unscalable.
We could keep on trying to fix the slop or rewrite the whole thing.
We rewrote the whole thing.
What We've Been Building: v1.0 Features
The problem with rewriting the entire backend is that we cannot release updates incrementally. It will come as an avalanche. For starters, this is what works on staging right now:
-
Completely automated and foolproof domain setup
No more failures, no manual configuration headaches. -
Auto-launch campaigns with real-time accurate updates
No need to press the button twice now. Launch and monitor with confidence. -
Spintax Support
Nested spintax even. Please don't try too many nestings. We will consider that a DDoS attack.

-
Email accounts created in bulk without crashing
Sorry for the earlier pains - this is now fixed. -
Subscriptions that don't suck
Prorated upgrades ... and subscribing to pro now actually subscribes to pro. -
Agency Plan
You can add teammates now. And also buy top-ups for more domains and inboxes.

Enhanced frontend fixes
Especially related to analytics since you can now see progress per lead.

What's Left: Testing Phase
Testing. We need to make sure the scheduler doesn't break when it has to send millions of emails (we're doing it via simulation right now, of course).
So far, it's going good. Once all tests are cleared, we'll do one final round on staging by running actual campaigns. And then ... the big release.
Thank You: To Our Early Supporters
We had no idea that our offering would have this much pull in the market. We never expected paying users during our beta stage, but we feel extremely grateful that you guys showed this much support.
Here's to all the OGs in Discord. WAGMI 🍻
And as a token of thanks, all paying users will be getting special discounts upon release. Yes, you kinda will have to resubscribe once the new backend is up because it's a new stripe account. We'll be there in Discord to help you with a smooth migration.
To the people reading this who have no idea what I'm talking about, join us on Discord. Seriously, even if you aren't using the product right now, we'd still love to have you be a part of the community and watch possibly the greatest experiment in the cold email space since ... I don't know, Instantly?
Anyways, we plan on turning this community into a hub of resources where sales teams and lead gen agencies can collaborate over the best practices (and other kinds of collaborations .. the kind that only happen in DMs .. please no harassment).
P.S ColdSend API coming soon next month. This time, we won't vibe code it first. Promise.
