Email mode and max email limit

I have selected Email mode for the forum and ‘Send me an email for all posts’. At the bottom of each email I am seeing the message:

Heads up: We send a maximum of 100 daily emails. Check the site to see the ones that might be held back. PS thanks for being popular!

Does this mean I am missing posts? It says to check the site but I don’t see how to know which ones have not been emailed. If I am missing posts can the max count be increased?

Well there certainly are not over 100 messages every day. So you aren’t missing anything currently.

Will look to see if it’s a limit we have any control over - it may be a limitation of the free hosting we receive.

OK, thanks Nick

(bla bla some extra text because apparently I can’t post a message shorter than 20 characters by replying via email)
