Frequently Asked Questions

How does Aerosend deliverability checker work?

Our email deliverability checker runs a full diagnostic on your sending domain and generates a deliverability report. It consists of clear scores and the exact fixes that are required to land in the inbox instead of spam.

All you need to do is enter your email, email sequencer and API key. We will analyse your DNS records, plus SPF, DKIM, and DMARC authentication and reputation signals across major inbox providers like Gmail and Outlook.

Here’s the playbook behind every check – Email Deliverability Guide

How do I test my email deliverability?

Email deliverability monitoring is the process of tracking where your emails are potentially landing by identifying patterns. You can test your email deliverability using the deliverability checker. Here’s how we monitor your email deliverability.

What does the deliverability checker test?

The checker inspects your domain’s DNS records, SPF, DKIM, and DMARC authentication. Additionally we check your domain reputation and blacklist signals that inbox providers use to decide whether your emails reach the inbox. Every result comes with an actionable fix.

What is a good email deliverability score?

A healthy sending domain typically scores 90% or higher, meaning authentication is correctly configured and reputation signals are clean. A lower score usually points to missing DNS records or authentication gaps. Learn how the deliverability score is calculated.

Is the email deliverability test free?

Yes. The deliverability checker is completely free and returns instant results with no credit card or signup. Aerosend is an email deliverability platform that also offers managed warmup and monitoring when you need ongoing support.
