Need some quick advice.

I hate holding convos on text, but I realized I was being so dry texting some of the girls I'm talking too, that they thought I had lost all interest in them. However when I started texting them again, they all seemed more interested like before. (One of them i didn't text for 1.5 weeks now during corona, can't let that happen again) after i contacted her once tho, she started texting me all the time . anyways thats not the point

I'm looking for statement texts examples i can use, so i dont have to hold a conversation with them over text, but still letting them know that i "remember them"

an example : "good morning, have a productive day"

do you guys know of any similar texts to this one i can use?
