Why every outbound team needs a deliverability audit

When outbound performance drops, most teams change the wrong things.

They rewrite copy. They tweak subject lines. They blame the list. They reduce volume.

Sometimes that helps. Often it doesn’t.

Because when emails stop landing in the inbox, the problem isn’t messaging - it’s deliverability. And deliverability issues are invisible unless you actively look for them.

That’s where a proper email deliverability audit comes in.

What an email deliverability audit actually is

A deliverability audit isn’t a vague “health check.”

It’s a systematic way to understand how inbox providers see your sending setup.

A good audit answers questions like:

• Are your emails landing in inbox, promotions, or spam?

• Do Gmail and Outlook treat you differently?

• Are authentication records configured correctly?

• Is your domain reputation helping or hurting you?

• Are technical issues blocking delivery before content is even evaluated?

Without these answers, every outbound decision is guesswork.

How to do a proper audit

A real audit checks fundamentals first - not copy.

• Authentication: SPF, DKIM, and DMARC alignment

• Domain reputation: how inbox providers classify your sending domain

• Inbox placement: where emails actually land across providers

• Infrastructure consistency: domains, mailboxes, IP behavior

• Early red flags: issues that will compound if volume increases

If these aren’t clean, no amount of personalization or clever copy will save your campaign.

How to run a deliverability audit without guesswork

To make this easier, we built a free Email Deliverability Audit tool that tests exactly what matters - without requiring setup, logins, or technical expertise.

The test shows you:

• Where your emails land (inbox vs spam)

• How different providers treat your sending

• Whether authentication is set up correctly

• Early warning signs before performance drops

It’s designed to give you clarity fast - so you know what to fix before scaling.
