Shared IPs, bad authentication, and weak infrastructure silently kill your campaigns. ESPMailHub gives you clean, dedicated sending infrastructure — so your emails actually land.
Most founders fix their subject lines. The real issue is what happens before your email is even opened.
Without proper DKIM, receiving servers can't verify your identity. Your email fails authentication before a human ever sees it.
Cheap ESPs put thousands of senders on the same IP. One bad actor tanks the deliverability for everyone on that server.
Bounces and spam traps signal that you're a bad sender. Gmail remembers. Domain reputation damage is extremely difficult to reverse.
Guided setup. No developer required. You're live in under an hour.
Add your sending domain with guided DNS instructions. SPF, DKIM, and DMARC are configured automatically.
We validate your records are live and correctly set up. Your domain gets a clean sending identity from day one.
Your emails route through dedicated sending servers — no shared IPs, no mystery reputation baggage from other senders.
Monitor inbox rates, bounces, and domain reputation. Get alerted before problems compound into permanent damage.
We cut the bloat. Every feature here exists to protect your domain and get you to inbox — nothing else.
Your own sending pool. No shared IPs. Your reputation is yours alone — no other sender can affect it.
Guided configuration with live validation. Fully authenticated from the first send. Gmail trusts you by default.
Automatic suppression on hard bounces and spam complaints. Domain reputation protection built in — not bolted on.
Open rates, click rates, bounce rates — all real data from pixel injection and link tracking. Not estimates.
Simple block builder for cold outreach. Import contacts, segment, and send — without drowning in settings.
Send transactional email or trigger campaigns programmatically. Full REST API with key management.
Early users lock in founder pricing permanently — grandfathered before paid plans launch.
