# Why isn’t my email arriving?
Check mailbox setup, DNS authentication, and delivery status without guesswork.

email DNS delivery

## Key takeaways
- MX records direct incoming mail to the right destination.
- SPF and DKIM help receiving systems verify outgoing mail.
- A refusal usually means the recipient or a required check needs attention.
Email depends on a few DNS records that answer different questions. IaGenify shows the values required for your domain; use those values as the source of truth when updating its DNS zone.
## Know what each record does
MX records tell other mail systems where to deliver incoming messages. SPF identifies which sending services are permitted for the domain. DKIM lets a receiving system verify a signature attached to an outgoing message. A DMARC policy tells receivers how to handle messages that fail those checks and where reports may be sent.
A typo or duplicate record can undermine a setup even when the rest looks correct. Compare the complete record name, type, and value with the instructions, and avoid publishing multiple SPF records for the same hostname.
## Read the delivery result
A refusal means the message was not accepted for delivery. Check that the recipient address exists, the sending domain is verified, and its authentication records are visible. A delayed message may still be retrying; use the delivery status to distinguish that from a final refusal.
## Check attachments and storage
Attachments can depend on the storage connected to your account. If a message arrives without an attachment link, review available storage and the attachment size, then try again with a smaller file if needed.

## Frequently asked questions

What does an MX record do?
It directs incoming mail for your domain to the destination that handles its mail.

What does a refused message mean?
The recipient did not accept the message. Check the address, domain verification, and authentication status. [← Back to Mail FAQs](https://help.iagenify.com/faqs/mail)
