Frequently asked questions

Yes. Every workspace includes up to 15 mailboxes, 3 domains and 5 GB of storage per mailbox at no cost — enough for most small businesses to run all of their email. You only need a domain you already own.

• •No credit card required to sign up
• •No trial timer that deletes your mailboxes
• •Transactional API included — not a paid add-on
• •Need more than 15 mailboxes? Contact us — $1 per extra mailbox per month

No. Your domain stays exactly where it is. You only add a few DNS records (MX, SPF, DKIM, DMARC) at your current DNS provider, and OquMail guides you through each one with copy-paste values.

• •Registration stays at your current registrar
• •Only DNS records change — not ownership
• •Works with Cloudflare, Namecheap, GoDaddy, Route 53, and more
• •See our blog for provider-specific walkthroughs

Yes. The free plan includes up to three custom domains in one workspace — useful for multiple brands, regional sites, or a separate marketing domain.

• •Each domain gets its own MX, SPF, DKIM, and DMARC records
• •Mailboxes are tied to one primary sending domain per address
• •Verify each domain independently in the admin panel

Yes. Your domain stays at your registrar and every mailbox is standard IMAP, so you can copy all your mail to another provider with Thunderbird, Outlook or Apple Mail, then point your MX records elsewhere. No export fees, no lock-in.

Yes. Every mailbox works in OquMail webmail and in any IMAP/SMTP client — incoming IMAP on mail.oqumail.com port 993 (SSL/TLS), outgoing SMTP on port 587 (STARTTLS), using your mailbox address and password. Settings are in the app under Connect to app (IMAP).

• •Incoming (IMAP): mail.oqumail.com, port 993, SSL/TLS
• •Outgoing (SMTP): mail.oqumail.com, port 587, STARTTLS
• •Sign in with your full mailbox address and mailbox password
• •Works with Outlook, Apple Mail, Thunderbird, and iPhone or Android mail apps
• •Webmail in any modern browser is always available too

Each mailbox can create API keys. You send mail with a single HTTPS request, and every message appears in your dashboard with full delivery logs. Keys can be configured as no-reply so recipients cannot respond.

• •POST JSON to the emails endpoint with your API key
• •Set fromName and reply-to behavior per message
• •View SMTP responses in delivery logs when something fails
• •Revoke compromised keys without touching DNS

Yes. Create matching mailboxes at your domain in OquMail, then copy your old mail over IMAP — add both the old account and the new OquMail mailbox to a client such as Thunderbird or Outlook and move folders across — before switching your MX records.

• •Copy old folders over IMAP with Thunderbird, Outlook, or Apple Mail
• •Lower DNS TTL before MX cutover
• •Create mailboxes in OquMail before flipping MX
• •See our migration guide on the blog for a full checklist

OquMail configures SPF, DKIM signing and DMARC for every verified domain — the authentication standards inbox providers require. Deliverability also depends on sending reputation, which builds as you send legitimate mail.

• •Verify all DNS records before bulk sending
• •Warm up new domains gradually — start with transactional mail
• •Never buy email lists or blast cold outreach from your primary domain
• •Monitor the deliverability dashboard for bounce spikes

Free for up to 15 mailboxes. Need more? Contact us — $1 per extra mailbox per month. We add them to your existing workspace as you hire, with no migration or DNS changes.

• •First 15 mailboxes, 3 domains, and 5 GB per mailbox remain free
• •$1 USD per month for each mailbox after the first 15, arranged by contacting us
• •Same webmail, IMAP/SMTP, API, and deliverability features on every mailbox

Mail is encrypted in transit via TLS between clients and our servers. We enforce authentication on every send, support role-based admin access, and let you revoke API keys and suspend accounts instantly.

• •TLS for webmail, API, and IMAP/SMTP client connections
• •SPF, DKIM, and DMARC protect your domain from spoofing
• •Per-mailbox API keys instead of shared SMTP passwords
• •Admin roles limit who can manage domains and users
