What we do

SPF, DKIM and DMARC setup

Correct authentication for every service that sends email for your domain.

Deliverability audit

A review of your domains, sending services, authentication and reputation.

Mailbox warm-up

Gradually building sending reputation on new domains and mailboxes before they carry real volume.

Website and form email

Reliable delivery for contact forms and system notifications.

When customers, partners or prospects stop receiving your email, or find it in spam, the cause is usually technical: missing or broken SPF, DKIM or DMARC records, a damaged sending reputation, or tools sending on your behalf without being authorized.

Shiptronix diagnoses the problem, fixes your authentication, and puts monitoring in place so your email keeps arriving where it should.

Signs you need Email Deliverability

  • Customers say your emails land in spam or never arrive
  • You recently started sending from a new tool, CRM or website form
  • You have received bounce messages mentioning SPF, DKIM or DMARC
  • You are planning cold outreach and want to protect your main domain

Who it is for

  • Businesses whose emails land in spam or go missing
  • Companies that send from several tools, such as Microsoft 365, CRMs, forms and marketing platforms
  • Teams responding to new sender requirements from Google, Microsoft and Yahoo
  • Organizations that want to stop domain spoofing and phishing

How we do it

SPF
We list every service that legitimately sends email for your domain, such as Microsoft 365, Google Workspace, your CRM, marketing platform and website forms, in a single SPF record that stays under the 10-lookup limit.
DKIM
We turn on DKIM signing for each sending service and publish its keys, so receiving servers can confirm your messages were not altered and really came from you.
DMARC
We publish DMARC in monitoring mode first, confirm every legitimate sender passes, then move to quarantine and reject so spoofed email using your domain is blocked.
Separate sending domains
For sales outreach we set up dedicated domains and mailboxes that point back to your main brand. If a campaign runs into trouble, your everyday business email is unaffected.
Mailbox warm-up
New domains and mailboxes start at low daily volume with real engagement and increase gradually over several weeks, so mailbox providers learn to trust them before campaigns begin.
List hygiene
Contacts are verified before sending to remove invalid, risky and catch-all addresses, which keeps bounce rates low and protects reputation.
Inbox placement testing
We send seed tests to Gmail, Outlook and Yahoo accounts to see whether messages land in the inbox, the promotions tab or spam, and adjust before scaling.
Reputation monitoring
We watch bounce and spam complaint rates, blocklists, and mailbox provider tools such as Google Postmaster Tools, and act quickly when something changes.
Compliance
Every campaign includes a clear sender identity, a physical address and a working one-click unsubscribe, in line with CAN-SPAM and the current Google and Yahoo sender requirements.

Frequently asked questions

What are SPF, DKIM and DMARC?

They are DNS-based standards that prove an email really came from your domain. Major mailbox providers now expect all three for reliable delivery.

Why is our email going to spam?

Common causes include missing authentication, a sending service that is not authorized, or reputation problems. An audit finds the specific cause.

Will turning on DMARC block our own email?

Not if it is done in stages. We start in monitoring mode and move to enforcement only once every legitimate sender is authenticated.

Do you work with Microsoft 365 and Google Workspace?

Yes, along with CRMs, marketing platforms and website form services.

Do I need to set up DMARC?

Yes. Google, Yahoo and Microsoft now expect senders to have SPF, DKIM and DMARC in place. DMARC also protects your domain from being used in phishing emails.

How do I enable DMARC for Microsoft 365?

Microsoft 365 needs DKIM signing turned on for your domain and SPF that includes Microsoft. DMARC itself is a DNS record you add at your DNS provider. We set up and verify all three.

What does a DMARC record look like?

It is a DNS text record at _dmarc.yourdomain.com, such as v=DMARC1; p=none. The policy can then be tightened to quarantine or reject once all legitimate senders pass.

Can you get us off an email blacklist?

We diagnose why a domain or server was listed, fix the cause and request removal where the blocklist allows it.

What is email warm-up?

Warm-up is the process of building a sending reputation for a new domain or mailbox by starting with small daily volumes and increasing them gradually. Sending large volumes from a brand new mailbox is one of the fastest ways to end up in spam.

How long does email warm-up take?

Most new mailboxes need two to four weeks of warm-up before they carry meaningful volume, and warm-up activity usually continues at a lower level while campaigns run.

Should cold email be sent from our main domain?

We recommend against it. Using separate, related sending domains for outreach protects the reputation of the domain your customers, partners and team rely on every day.
