Questions about Email
Your mailbox only shows what arrived. Whether anything arrives at all is decided by a few lines in your domain's DNS.
Why your domain decides where your mail goes
The MX record is the delivery address of your domain. Before a mail server somewhere else hands a message over to you, it looks there. If the old provider is still on record, your mail gets delivered dutifully into a mailbox nobody has opened since the move.
The other direction is about trust. SPF, DKIM and DMARC answer a single question for every receiving mail server: did this message really come from you? If one of the three records is missing or contradicts the others, your messages still go out. At the other end they land in the spam folder, or they get turned away on the spot.
Why it rarely shows up straight away
Email does not report faults. It delivers, or it does not. A wrong MX record therefore only comes to light when somebody rings up and asks why they never got an answer. With the SPF record it usually takes even longer, until one day an important customer wonders why they never hear from you.
Both have been sitting in DNS the whole time. You just have to know what to look for. That is exactly what the checks below do: they read the records of your domain, put them into plain words, and name the place where you can change something.
The questions in this area:
- Is my domain verified for Google Workspace?
- Is my newsletter tool allowed to send in my name?
- Can someone send email in my name?
- Why is no email reaching me?
- Why can't Outlook find my mailbox?
- Is my domain or my mail server on a spam blacklist?
