When to send

That's entirely too early. Invitations should go out 6-8 weeks before the wedding.

You Can Mail Them Anytime You Want Honestly, If You Have A Lot Of Out Of Town Guests It'd Be Best To Send Them Out A Little Earlier. We Have The Same Wedding Date, I Plan On Sending Mine Out In July-August.

I sent my invites out a little earlier than "normal" for travelling guests and due to not sending out all of our save the dates because of covid, all the restrictions, and not being sure if we were still going to be able to have a wedding at that time. So we sent our invites out beginning June 1st for our August 22nd wedding so they had plenty of time to decide about attending prior to our Aug 1st RSVP deadline.

6 - 8 weeks is customary unless it's a destination wedding, then you want to add 2 - 3 extra weeks to allow for those traveling and needing to get hotels, flights, etc.

Especially since you sent STDs, eight weeks is PLENTY of time. Most guests still aren't going to RSVP until close to the due date. Sending them early does nothing to motivate guests, it just gives them longer to procrastinate. Daughter got married in mid-January, and for her, eight weeks meant the invites went in the mail Thanksgiving week and the RSVP date was Christmas day. Even in the middle of the holidays, that was plenty of time and all but 10 guests (representing 3 households) had responded by the due date. I think your original plan sounds great!

I would mail them 6-8 weeks before your wedding. I got married 10/5/19 and we had a 9/13/19 RSVP deadline. We mailed our invitations the second week of August. That put us right at the 7 week mark.
