How to keep Delivrie email out of spam: authentication, warming up a new domain, bounce and complaint thresholds, content, list hygiene and what to do when mail goes to spam.
Deliverability is whether your email reaches the inbox rather than the spam folder. Mailbox providers decide based on your domain's authentication, your sending history and how recipients react.
mail.acme.com, so app email and team email don't share a reputation.| Metric | Keep it under | What happens above it |
|---|---|---|
| Bounce rate | 4% | Providers start blocking you, and Delivrie pauses your sending |
| Complaint rate | 0.08% (and never above 0.3%) | Gmail and Yahoo filter or reject your mail, and Delivrie pauses your sending |
Delivrie checks every account once an hour. If, over the last 7 days, more than 4% of your emails bounced (once you've sent at least 100) or more than 0.08% were marked as spam (once you've sent at least 1,000), sending is paused for the whole account. Sends then fail with 403 sending_paused, and your team admins get an email explaining why. Emails to the test addresses don't count.
To resume, find the cause (usually an old or imported list, or a sign-up form without validation), remove the bad addresses, and email support@delivrie.io with what you changed. This protects your domain's reputation as well as everyone else's.
Watch both in Metrics or with GET /metrics.
A new domain has no reputation. Start with your most-engaged recipients and grow over a few weeks:
| Week | Emails a day |
|---|---|
| 1 | Up to a few hundred |
| 2 | 1,000 to 2,000 |
| 3 | 5,000 |
| 4 onward | Double while bounces and complaints stay low |
Transactional email (sign-ins, receipts) warms a domain naturally, because people open it.
delivered means the provider accepted it; where it filed it is the provider's choice.PASS on all three.
