250ok for Email Marketers

Drive better inbox placement and engagement like it’s your business.




72% of consumers say that email is their preferred form of communication with companies they do business with. To serve them, let us help you deliver more mail.


Gain access to senior deliverability experts

You can lean on our professional services team to simplify deliverability for you and your team. With decades of combined experience consulting name brands and ESPs, we provide real expertise and dedicated support instead of junior-level script reading. Getting maximum value out of email programs is what our consultants and software deliver, every day.

Protect your brand and your reputation

With a 250% surge in phishing attacks over the past year, protecting your customers and brand has become a priority. As part of Reputation Informant, our DMARC dashabord gives you unprecedented visibility into email-based abuse like phishing and spoofing. Additionally, we monitor a spam trap network of over 30 million domains (and growing) to identify questionable sending behavior that damages your reputation.


Centralize your render testing and spam filter testing

See how your message will appear to all of your recipients and test spam filtering before sending a message. Leverage our out-of-the-box integrations with Litmus and Email on Acid to centralize your email rendering and spam filter testing in a single portal supporting over 30 email clients and devices.

Measure engagement and understand thy customer

With Email Informant’s real-time analytics, you gain visibility into who your customers are, where they’re located, what devices they’re using, how long they’re reading your messages, and more. Simply embed a tracking pixel in each message allows you to glean meaningful insights about customers engage with your campaigns.
