Question 1

What is email deliverability?

Accepted Answer

Email deliverability is the ability of your emails to reach recipients' inboxes rather than being filtered as spam or blocked entirely. It depends on factors like domain authentication (SPF, DKIM, DMARC), sender reputation, and email content.

Question 2

What are SPF, DKIM, and DMARC?

Accepted Answer

SPF (Sender Policy Framework) specifies which servers can send email for your domain. DKIM (DomainKeys Identified Mail) adds a cryptographic signature to verify emails weren't tampered with. DMARC (Domain-based Message Authentication) tells receivers what to do when SPF or DKIM fail.

Question 3

Why are my emails going to spam?

Accepted Answer

Common causes include missing or misconfigured authentication records (SPF, DKIM, DMARC), poor sender reputation from high bounce rates or spam complaints, sending from a new domain without warming up, or content that triggers spam filters.

Question 4

How do I fix email deliverability issues?

Accepted Answer

Start by checking your SPF, DKIM, and DMARC records using this tool. Ensure all three pass. Then check your sender reputation using Google Postmaster Tools, reduce bounces by cleaning your email list, and avoid spam trigger words in your content.

Question 5

What is a good deliverability score?

Accepted Answer

A score of 90+ indicates excellent deliverability with all authentication records properly configured. 70-89 is good but has room for improvement. Below 70 suggests missing or misconfigured records that could cause emails to land in spam.
