"The Deliverability Machine"

TL;DR

Ongage is a high-performance email marketing platform built for deliverability. Multi-ESP routing + deliverability dashboard + in-depth testing. Reach more people, make more money

Pros

  • Deep deliverability controls

  • Advanced segmentation

Cons

  • Requires technical skills
  • Not built for small lists
  • UI isn’t the flashiest

What is Ongage?

Ongage is an email marketing platform where you can optimize deliverability by switching between multiple ESPs on the fly, automate like a boss, and unlock deep segmentation and personalization at scale.

Our Verdict — Best For Deliverability Nerds

The Best Part:

  • Inbox like an emperor. Ongage connects to multiple ESPs to route traffic, multi-SMTP routing, IP management… everything to get you higher open rates and lower bounce rates. Your open rates will thank you.

The Worst Part:

  • Not for noobs. If you just want to send a few emails per month, Ongage is probably gonna feel like flying a spaceship to get to the grocery store.

Get it if you want your emails to consistently reach the inbox.

Best For

Ongage is best for power users, data-driven teams, and marketers who treat their email as a performance channel, not just newsletter blasts.

Top Features

  • Deliverability dashboard. Monitor inbox placement, bounce rates, delivery logs, ISP response codes, complaint rates, sender reputation and much more. You’ll dodge that Promotions tab like Neo in The Matrix.

  • Pre-send testing. Ongage checks your email health in order to send. Think spam score, broken links, missing previews, and rendering issues… all gone.

  • Smart routing. Set auto-rules based on metrics like open rate, device, geo, and even audience fatigue. It’s like smart traffic lights for your emails.

  • Real-time pulse. Track campaign performance by SMTP, by segment, or by behavior, and tweak them as you go.

  • Squeaky-clean lists. Ongage doesn’t just scrub lists. Suppression lists are automatically enforced to keep problems from happening in the first place.

What do customers love about Ongage?

  • Jaw-dropping inbox rates
  • Multi-SMTP flexibility
  • In-depth analytics and reporting tools
  • White-glove support
  • ESP routing
