Okinta sends bulk email (newsletters and similar campaigns) through shared sending infrastructure. One workspace with bad lists or spammy content can hurt deliverability for everyone. To keep inboxes healthy, Okinta scores each workspace on how recipients react to mail and adjusts how fast you can send.
This applies to Professional Email bulk sends—not to personal SMTP / IMAP threads in Conversations, which use your own mailbox.
Every workspace sits in a sending pool. The pool reflects recent results: opens, spam complaints, and bounces. You can think of it as a trust level for bulk sending.
New sender — You are building a sending history. Bulk sends go out in small batches until Okinta has enough data.
Low risk — Strong engagement and low complaints and bounces. You can send at full speed within your plan.
Moderate risk — Some metrics need attention. Sending continues, but you should clean your list and review content.
High risk — Several metrics are weak. Bulk sending is heavily throttled until stats improve.
Quarantine — Sending is paused for bulk mail until Okinta support reviews your account.
Open rate — How many recipients opened your emails compared to how many were sent. Low opens often mean an old list, weak subject lines, or mail landing in spam.
Spam complaint rate — How many people marked your message as spam, compared to opens. Even a small number matters.
Bounce rate — How many addresses rejected your mail (invalid mailboxes, full inboxes, blocked domains), compared to sends.
Okinta recalculates pools daily using recent campaign data. Sudden spikes in complaints or bounces can move you to Quarantine immediately.
If your workspace is new to bulk sending, Okinta does not release your full list at once. Instead:
1. The first 100 mailable contacts receive the campaign (most recently engaged contacts first).
2. Okinta waits 6 hours so bounces, opens, and complaints can arrive.
3. If stats look healthy, the next batch of 100 goes out. If not, you may see a warning or a pause.
This repeats until you have sent at least 500 bulk emails, been a customer for 16 days, and spent 14 days in the new-sender pool—with acceptable stats throughout.
While warmup runs, the campaign stays in progress; you will not blast the entire list in one shot.
Workspaces that already sent bulk mail through Okinta before reputation controls rolled out are treated as established senders. They skip the new-sender batch ramp but remain in the normal pool system—good stats keep you in Low risk, bad stats can still trigger warnings or Quarantine.
On contact import and before newsletter recipients are queued, Okinta checks each address:
Invalid format is skipped.
Known disposable (throwaway) domains are skipped.
Domains without proper mail DNS (MX records) are skipped.
Contacts already marked bounced, spam, unsubscribed, or otherwise non-mailable are excluded.
Imports show fewer rows added when addresses fail these checks—fix typos or remove bad data and import again.
Professional Email must be connected and your domain must pass SPF, DKIM, and DMARC verification before newsletters go out.
Free mailbox domains (Gmail, Outlook, Yahoo, and similar) cannot be used for Professional Email—use an address on your own domain.
Only email people who agreed to hear from you.
Remove bounced and unsubscribed contacts promptly.
Re-engage or remove contacts who never open mail.
Send valuable content with clear sender identity—do not mimic banks, government, or unrelated brands.
Make unsubscribing easy; a clean unsubscribe is always better than a spam report.
Warm up large migrated lists gradually—start with your most engaged segment, not the whole database on day one.
When you are in Quarantine, new newsletter batches will not send. One-to-one Conversations email via SMTP may still work unless support flags abuse.
Contact Okinta support from the in-app Help menu. Explain what you changed (list source, content, frequency). Support can review stats and lift a pause when the account is safe to resume.
Pool and metrics for your workspace are available to admins via the email reputation API while we add in-app charts under Settings → Emails.
Watch bounce and complaint rates on individual campaigns in Audience → Content creation after sends complete.
