Email deliverability & DNS

Your email sends. But it lands in spam, bounces or disappears.

Axon1Pro helps businesses troubleshoot Microsoft 365, Google Workspace, hosting email, website SMTP and transactional email when delivery changes after a migration, DNS update, domain move or configuration change.

Email delivery depends on several systems working together

MX records

Mail must route to the intended provider after a domain, DNS or nameserver change.

SPF

Authorized sending services need to be represented correctly without creating conflicting or invalid records.

DKIM

Microsoft 365, Google Workspace and other services use domain signing that must match the sending environment.

DMARC

Policy and alignment can affect how receiving systems treat messages that do not authenticate as expected.

SMTP & website mail

Forms, apps and transactional systems need a reliable authenticated sending method and correct sender identity.

Migration & coexistence

Old and new mail systems, aliases, forwarding and DNS propagation can create confusing partial failures during migration.

Typical questions people ask

“Why is my business email going to spam?”

“My email stopped working after I changed nameservers.”

“Microsoft 365 can receive email but cannot send.”

“Google Workspace says my DKIM is not configured.”

“My website form emails are rejected.”

“Some customers receive my email and others do not.”

“My domain migration broke email.”

“ChatGPT told me to add SPF/DKIM/DMARC records. Can someone do it safely?”

Our troubleshooting path

Confirm which mail platform should send and receive for the domain.

Review DNS, authentication records, aliases/forwarding and SMTP settings.

Check bounces or delivery symptoms and isolate sender, DNS, provider or recipient-side issues.

Make controlled changes and retest without unnecessarily disrupting working mailboxes.

Email problems often start somewhere outside the inbox.

Tell us the domain, mail provider, recent DNS/migration changes and what senders or recipients are seeing.
