Having Same issue. I’ve noticed this happening on multiple occasions lately. I’ll send out an invoice and then find out the client never received it. Go back and it never sent or had a message error in sending. This isn’t acceptable in my eyes. I’m having to double check each time that it went through and is taking up my time when it should be a fire and forget process. Yes the email addresses are correct. Anyone else having this issue or know a better way to deal with it?                         My CC Pay
