Max # of "My Phrases" in Speedchat?

[Clover Featherquack]

I'm sure this has been answered before, but I can't seem to pin it down. What is the max number of phrases you can purchase for My Phrases in Speedchat? Also, is there any way to erase some once you reach the limit, or is that just all she wrote?

Thanks!

You can have up to 25 phrases, it seems.
To erase a phrase, once you have 25, you will have to erase one before it lets you take another from your mailbox.
