What is a good email deliverability rate in 2026?

The global average inbox placement rate is around 83% according to Validity's 2025 Benchmark. Unspam.email's 2025 corpus data puts real visible inbox reach closer to 60% when accounting for all sender types and filtering behavior. For compliant senders with clean lists and strong engagement, inbox placement above 90% is achievable and should be the target. Consistently below 80% signals something needs attention in your sending program.

Why are my emails going to spam even though I have SPF, DKIM, and DMARC set up?

Authentication confirms your identity; it does not guarantee inbox placement. Unspam.email's 2025 analysis found that fully authenticated mail still experienced spam placement rates above 30%. After passing authentication, providers shift to behavioral evaluation: do recipients actually engage with what you send? Low click rates, high deletion rates, and complaint rates will route you to spam regardless of perfect authentication.

What is the difference between email delivery rate and email deliverability?

Delivery rate measures what percentage of sent messages were accepted by the receiving server without a bounce. It says nothing about where the message went afterward. Email deliverability (inbox placement rate) measures whether the message reached the inbox rather than the spam folder or a filtered tab. You can have a 99% delivery rate and a 60% inbox placement rate at the same time. That gap is where most performance is lost.

What changed in Google Postmaster Tools in 2025?

Google retired the legacy Postmaster Tools v1 interface in October 2025. The Domain Reputation and IP Reputation dashboards are permanently gone. Postmaster Tools v2 evaluates senders on a binary Compliance Status (Pass or Fail) across authentication, unsubscribe compliance, and spam rate. If your status shows Fail, your mail is at risk of permanent SMTP rejection. Check the Compliance Status tab weekly.

How long does it take to fix poor email deliverability?

Authentication fixes take effect within hours of publishing corrected DNS records. Reputation recovery typically takes 4 to 12 weeks of consistent best-practice sending: clean lists, complaint rates below 0.1%, strong click engagement. Severe reputation damage can take several months. The only path is sending well to people who want your mail, at consistent volume, over time.
