What we've shipped, what's next, and what we're weighing

Active reputation management across 15 MTAs and 3 IP pools. Watches ISP signals every 30 seconds and adjusts sending per-domain so one bad day on one domain doesn't take down the rest.

Separate reputation scores for transactional and marketing subdomains. One rough campaign cannot drag down your OTP delivery — the lanes don't talk.

Public SPF, DKIM, DMARC and MX audit at /free-deliverability-check. Runs over Cloudflare DNS-over-HTTPS. No signup, no email gate, no upsell wall.

Built and running across three IP pools — mayukaa, ashtavin, astavin. Pool-level isolation means a deliverability incident on one neighborhood doesn't bleed into the others.

Full event coverage: delivered, bounced, deferred, blocked, complained, opened, clicked, unsubscribed. Signed payloads, retries with backoff, a per-endpoint dead-letter view.

Honest side-by-side breakdowns versus SendGrid, Amazon SES, Mailgun, Brevo, Resend, Postmark, Mailchimp Transactional, SparkPost and SMTP2GO. No fake "we win every row" charts.

Two free 12-page PDFs. One on how ESP pricing actually works once you do the math. One on the 2026 ISP signal shifts — what changed at Gmail, Outlook, and Yahoo and what to do about it.

One API, one reputation graph, two outbound lanes — priority for OTPs and alerts, throughput for campaigns. Pick the lane on the send call, not the account.

Per-domain sending speed adjusts itself based on real-time ISP feedback. Bounces tick up, the throttle pulls back. Signals clean up, it opens back up.

A single 0-100 score per domain blending bounces, blocks, complaints and deferrals across multiple time windows. One number to glance at, all the underlying signals one click away.
