About this email
This email from Hunter.io informs the user that they have nearly exhausted their allotted 25 search credits. It encourages upgrading to a premium plan to continue using the service, providing a clear call-to-action link and an offer for direct assistance. The tone is polite and supportive, structured simply with a greeting, main message, call to action, and a closing signature.
Hunter.io journey
Why this works
**Why this works.** The subject line uses "about to reach" instead of "upgrade now," which creates urgency without sounding salesy and gets the user to open before they've already mentally rejected a pitch. The pattern here is "name the constraint, not the solution"; you can lift it for any quota-reached or limit-hit email where you want users to upgrade because they feel friction, not because you told them to.
