It all depends on your ISP and the receivers' ISPs. Technically, there is of course no limit. But your ISP might think you're sending spam, so it's good to inform him that this is not the case.

Much harder is to convince the receivers' ISPs that you're not sending spam. I had problems with gmx, a large German ISP: they were not accepting more than so-and-so many (maybe some 1000) mails from me to non-existant accounts per 24h. That sounds a lot, but since I was sending a large mailing list, there were always too many no-longer existant email addresses.

As far as I know, there was no way of convincing gmx that I was not sending any spam, but a newsletter. I don't think they have a procedure for that. So, unless you are really important, they will just ignore you.

And then there are open blocklists, like spamhaus, that might somehow list you. They might be used by many ISPs around the world. In such a case, you can usually contact them and have your record cleared.
