The first goes to investors. The second goes to customers. They share almost nothing, and most advice on startup cold email quietly blends them.
We have measured data on the investor one. Founder to investor intros reply at 3.9%, and the volume behind that is substantial, so it is a number worth trusting.
We do not have a clean measurement for founders emailing prospective customers as a distinct pattern, so this page does not publish a rate for it. The template below is included because founders need it, and it is built on what works across every other segment we do measure, not on a figure we invented for this one.
If you only take one thing from that: be suspicious of anyone quoting a precise reply rate for startup customer outreach. It is rarely isolated cleanly.
For investors, lead with traction and be specific about the ask. For customers, lead with the problem in their words, not your product in yours. The most common founder mistake is using the investor email on customers, where the traction paragraph reads as irrelevant.
Hi [First name],
We have gone from thirty to sixty paying teams since spring, mostly through outbound rather than spend, and the retention is holding.
Raising a seed round now and your name came up twice from founders in the space.
Worth fifteen minutes, or should I send the deck first?
Hi [First name],
Teams at your stage usually end up with one spreadsheet that somebody rebuilds every week and nobody fully trusts.
We built our product after living with exactly that, and it is now handling it for a dozen teams your size.
Worth a look, or is this already solved for you?
Join us to elevate your outreach!

For investor intros, around 3.9% on measured data, against an all industries median of 0.74%. For customer outreach we do not publish a figure, because it is not isolated cleanly in our data and a made-up number would be worse than none.
For investors, yes. An intro from the founder is the format investors expect and a delegated one reads as a fundraise being run by committee. For customers it matters less than whether the email is specific.
One number that is genuinely load-bearing, not a paragraph of them. Investors read hundreds of these, so the email that states one meaningful figure and the ask clearly outperforms the one that lists everything.
Yes, and for many startups it is the only one available before there is an audience or a budget. The constraint is research capacity rather than sending volume, since the emails that work name something specific about the recipient.
