Sending single custom emails is much more effort than bulk-mailing a huge list operationally. Sending bulk can be accomplished by uploading a csv of emails to some enail bulk sender versus code to run at the correct time for the correct user... way easier in bulk and way cheaper

Is it truly much more difficult? At worst you could batch them by week and registered email, a one-liner can generate the list of destinations, and then you send that to your newsletter-sender-service and call the email "your cert is expiring next week".

It is easy to think something like this is easy until you attempt to do it.

Are you really questioning a free SSL Certificate system when it says something is too complex and not worth it?

If you ever set up a free SSL before LetsEncrypt, you'd know they're amazing and you can trust them not to lie to you, especially about this where they've outlined the reasons clearly.

Of course it's more difficult.

You are talking of a volume of around 600 000 000 domains (based on a plot on their website) that try to renew at best after 8 weeks. And that's just default profile, there are 160h certs profiles now [0].

You think they will ever send nearly as much as (at least) 75 million newsletter mails weekly? Sendgrid's highest value in their pricing slider is 1,25 mil a week.
