I had tested two eblasts before sending them, and both of them went out with broken links. One platform was RE NXT and the other was CORE. I sent a test to my work and my personal email so I could check on my desktop and through personal mobile just to be sure. They went out successfully, but people emailed me back that the link to our donation page was a 404 error. I tried the link in the email they sent, and it was a 404. I copied the email, sent a test again to myself, and it worked.
I tried with both the HTTP:// format and with the address the tool suggested I use.
Can anyone shed light on this wicked glitch?
