Not exactly.

These emails all go to users who have signed up for an account. Traffic is weird right now (domain migration in progress), but I was getting ~250-350 user signups a day.

I send a monthly newsletter to users who have been recently active, a welcome sequence of 2 or 3 emails depending on where you sign up, and have an abandoned cart sequence of 3 emails (here's the link to your video / your preview will expire soon / your preview has expired).

Both of those channels (newsletter / automated sequences) have opt-outs, but the automated ones see pretty good engagement. The max number of automated emails is in the 5/6 range before unsubscribes, so it only takes ~3-4 emails per user to get up to 1k/day -- especially when you toss in another 100 or so for normal password resets, receipts, order emails, etc.
