I'm a business management student doing an internship at a small company. They publish an e-mail newsletter through a digital marketing website every month, and I was going to publish it yesterday. Everything seemed to be fine until I hit "Send" and it asked me to authenticate the domain, with spf and DKIM values. At that time I had absolutely no idea what "domain" even meant, but I ended up having to learn how to do those changes and get the job done.
I figured out how to access the DNS management page, found our address on the list, and clicked something that translates to "Add Zone" (there was no zone previously). It asked me for "Name of the zone", where I wrote the web address, and "IP", it said that if I didn't know the value I could use 1.2.3.4 for now, so that's what I did.
I didn't make any change or alter any values except for adding two TXT entries (there were none), one for the spf and another one for the DKIM, with the values the marketing website told me to insert. I wasn't sure I had done everything correctly so I sent them a print-screen and they told everything about those 2 entries was fine and I just had to wait.
This was more than 24hours ago and I'm starting to get nervous. I read that it could take up to 48hours, but I also read that the TTL value is the number of seconds it takes to update, and that is set to 4hours for each of those records. Why hasn't anything changed yet? I checked with https://www.whatsmydns.net/ and it doesn't show the new values.
I know this is probably a very simple problem, but I didn't know where else to ask, and if I haven't solved this problem by Monday they'll kill me, because this is the first time they've had a problem with sending the newsletter and it looks like it's my fault because it happened right when I took over the task of publishing it.
I don't mind waiting the 48hours (which will have passed in about 15 more hours), but is there any way to be sure that at the end the values will have changed? Could there be some problem that will prevent those values from updating?
I'm not sure what information I can provide since I have no idea which info can be a privacy risk for the company if made public, but I'll try my best to help you help me :)
Very much appreciate any help!
