Can i say thank for the tip in inbox?

[abderabby884]

I forgot to say thanks! That's why I thank him  in the fiver inbox or chat box today! Now I feel very nervous about it! Will it block my account?

It's absolutely fine.
Fiverr always encourage to Thank your buyer when you receive any tips.

Usually you can't thank your buyer for the tips in order page as tips info available after the completion of the project. And when you click on thank you button, fiverr will take you to the inbox automatically.

Stay relaxed.

Fiverr even encourages you to thank the buyer if they tip you. Adding to what @seven_sign said, just keep in mind that you should never send unsolicited messages to buyers or sellers. Thanking them for a tip is absolutely ok, but don't contact them to ask for more work, reviews and so on. That would be considered spam.

Yes, you can thank your buyer but not to try to contact for other services.

Thanks.
