A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

I think it's a good idea, everyone should be automating this anyway.

Providing expiration notifications costs Let’s Encrypt tens of thousands of dollars per year

Not doubting them, but I don't understand how that's possible.

Storing the email addresses and expiration dates takes an irrelevant amount of storage space, even if they had billions of cutomers.

Sending the emails should also not cost thousands, even if a significant amount of customers regularly let their certificates expire (which hopefull isn't the case).

So where are the tens of thousands of yearly costs coming from?

Transactional email services are about $15 per 10,000 emails. I'll round down to $10 to consider b2b deals and let's just say it's $10,000 per year. That would be like idk 84k emails a month.

Keep in mind this doesn't consider the DB hosting and the processing of expiring emails and salaries, so yeah, I could see it.

Edit: before anyone yells at me. I can't math.

Not yelling, but pointing out, to people who also dont math, that if we assume $10 per 10k emails (or $1 per 1k, for simpler math), that’d be $84 for 84000 emails in a month, so you need to add another 0 to the figure (ie 840k emails in a month)
