Email deliverability.
Keep password resets, receipts, and campaigns out of the spam folder across Gmail, Outlook, and Yahoo. Verify SPF, DKIM, and DMARC in minutes, separate transactional and marketing IP pools, and automatically block repeat sends to hard bounces and spam complaints.
Trusted every day by teams that
build world-class software.
Spot DNS and bounce issues
before the next send.
When a customer reports a missing email, ask Bird MCP to verify your sending domain and check whether their address is on the suppression list. Your coding assistant or support tool can catch unverified DNS records and past hard bounces in seconds.
Verify SPF, DKIM, and DMARC
to stay out of the spam folder.
Missing or misaligned DNS records are one of the fastest ways to land in spam at Gmail and Yahoo. Bird generates the exact DKIM, return-path, and DMARC records for your domain and handles SPF alignment on a return-path CNAME, leaving your root SPF record untouched.
Copy the generated hostnames and values into your DNS provider, and Bird verifies each record automatically.

Block hard bounces automatically
to protect your sender reputation.
Repeatedly emailing dead addresses or recipients who reported spam damages your sender score across mailbox providers. Bird automatically suppresses hard bounces and spam complaints before the next send, and lets your team inspect the bounce diagnostic or clear an address after a customer fixes a typo.
See where your emails land
across Gmail, Outlook, and Yahoo.
An accepted delivery event does not tell you whether a message reached the primary inbox or went straight to spam. Use Inbox Insights to monitor inbox versus spam placement across major mailbox providers, inspect deferral reasons in real time, and run seed tests before launching a major campaign.
Isolate your traffic with dedicated IP pools so a high-volume promotional blast cannot hurt the sender reputation of your password resets and receipts.
Email deliverability, explained.
Does domain verification guarantee inbox placement?
No. Passing SPF, DKIM, and DMARC proves your domain is authentic, which mailbox providers require before evaluating your mail. Whether an email lands in the primary inbox or spam still depends on your IP reputation, bounce rate, and recipient engagement. Use Inbox Insights to track actual inbox versus spam placement across providers.
Do I need a dedicated IP?
Lower-volume senders typically get better results on Bird's managed shared IP pools, where steady traffic keeps the pool warm. When you send consistent high volume, dedicated IPs and separate IP pools let you isolate transactional traffic like password resets from marketing campaigns, paired with automated warmup schedules.
How are marketing unsubscribes handled?
Hard bounces block future sends across traffic types to protect your sender reputation, whereas marketing unsubscribes and spam complaints stop promotional sends without blocking critical transactional emails like receipts or password resets. You can inspect the exact suppression reason in the dashboard or via the API before updating a recipient's status.
