In plain English

Deliverability simply means “does my email reach the inbox?” Most problems come from missing security settings or sudden bulk sending — both fixable without deep technical knowledge.

Practical next steps

  1. Confirm SPF, DKIM, and DMARC are published and passing
  2. Send gradually when starting — avoid huge blasts on day one
  3. Use a real From address on your domain, not a personal Gmail
  4. Check delivery logs when a message bounces or disappears

Mistakes to avoid

  • Using a personal @gmail.com or @yahoo.com address for client work
  • Skipping DNS security records (SPF, DKIM, DMARC) and wondering why mail goes to spam
  • Forwarding domain email to Gmail instead of using real mailboxes
  • Letting former employees keep the only password to a shared inbox

Common questions

How long does the small business email deliverability checklist take for a small business?

Most teams finish domain connection and first mailboxes in under an hour. DNS propagation is often minutes; in rare cases wait up to 24–48 hours. OquMail shows live verification so you know when you are ready.

Do I need technical experience to set up business email?

No. If you can log into where you bought your domain and paste a few lines of text, you can set up professional email. OquMail guides you step by step and verifies when DNS is correct.

Can my small team use business email for free?

Yes. OquMail's free plan includes up to 15 mailboxes on your own domain with webmail, guided SPF/DKIM/DMARC setup, and a transactional email API — no credit card required.
