My bot is hitting limits, how do I avoid this?

When sending messages inside a particular chat, avoid sending more than one message per second. We may allow short bursts that go over this limit, but eventually you'll begin receiving 429 errors.

If you're sending bulk notifications to multiple users, the API will not allow more than 30 messages per second or so. Consider spreading out notifications over large intervals of 8—12 hours for best results.

Also note that your bot will not be able to send more than 20 messages per minute to the same group.

Don't forget that bots that are sending long messages (over 500 characters approx) will hit limits more easily than those that are sending shorter messages.
