Ask a founder to recite their company’s brand voice guidelines and most can manage a sentence or two - warm but direct, expert but approachable, something like that. Ask the same founder what their onboarding email actually says, word for word, and almost none of them know. It was written once, usually by whichever engineer set up the transactional email tool, using whatever placeholder copy shipped with the template. Nobody has opened it since.
That is a strange gap, because the onboarding sequence is read at a rate no other email a company sends will ever match. A promotional newsletter is lucky to clear 30 percent opens from an engaged list. A welcome email, sent to someone who just signed up and is actively looking for confirmation that they did the right thing, routinely clears 60 to 80 percent. It is, by a wide margin, the most-read piece of writing most companies will ever produce - and the one least likely to have had a second pair of eyes on it.
The moment the email arrives in is unusually generous
A new user opening a welcome email is not skimming for reasons to leave, the way they might be with a support ticket or a churn survey. They just made a decision to try the product. They are, for the next few minutes, more favorably disposed toward the company than they will be at almost any other point in the relationship. That is a rare kind of attention, and most companies spend it confirming an email address instead of using it.
The founders who get this right treat the first email as a compressed version of the pitch they’d give in person - what the product actually does, what to try first, and a voice that sounds like a person rather than a legal disclaimer. The founders who get it wrong let the default template speak for the company, which means the company’s actual first impression was written by whoever built the tool the company happens to use, not by anyone who works there.
Where the sequence usually breaks
The first email is often fine, because at least someone thought about it once. The second and third emails in the sequence - the ones that fire three days and seven days later - are where most companies go quiet or generic, because nobody assigned ownership of the whole arc, only the first message. A new user who hears nothing specific for a week concludes, reasonably, that the product doesn’t have much more to say to them.
What to actually check
Read your own onboarding sequence today, from a fresh account, the way a new user would. Time how long it takes before the emails say anything specific to what that user actually did in the product versus generic encouragement that could apply to anyone. If the answer is “never,” that is not a small copy problem - it is the best-read channel the company owns, sitting unmanaged, while the marketing team debates font choices on a landing page a fraction as many people will see.
