Hi Donna. I don't know anything about this magazine, but it could be a new one.
The best approach is to ask for more information. Ask where you could find a copy of their magazine or whether it's an e-zine. Ask her what type of content she is looking for.
I'm pretty sure it's not the Mary: Literary Magazine I found in a search (yikes!). However, Sounja is listed on Linked-in as the editor of Mary! Magazine. So either it doesn't have much of an on-line presence yet, or it's a relatively new publication.
Certainly worth asking some questions, and there's no harm doing that. I doubt it's a scam, as anyone can go to the free reprints section if they want material for their magazine (without paying a cent). It's probably legitimate, but the main thing is whether the platform of the magazine is one that fits your writing. So ask away, and let us know how it turns out.
