submitting to micro lit mags?

I’m fairly new to submitting and just had my first acceptance (yay!) but it’s with a very small lit mag. I’m wondering if it’s still worth mentioning in a cover letter or bio, or if editors only care about “big name” publications.

ALSO Part of me worries the only reason I got accepted is because the magazine is small and maybe accepts most submissions. Has anyone else felt this way after an early publication?
