What is Email Deliverability?

Quick answer

Email deliverability is the ability of your emails to reach recipients’ inboxes rather than spam folders. It depends on sender reputation, authentication (SPF, DKIM, DMARC), content and list quality.

High deliverability means your campaigns actually get seen. Using your own authenticated domain and SMTP, plus clean lists, keeps you out of spam.

Opsidrive lets you send from your own SMTP and domain, improving deliverability and keeping emails on-brand.

How to improve deliverability

  • Authenticate your domain (SPF, DKIM, DMARC)
  • Use your own SMTP and sending domain
  • Keep lists clean and engaged
  • Avoid spammy content and sudden volume spikes

Yes — send from your own SMTP and domain for better deliverability and branding.
