250ok

250ok is a great tool for companies that have recently switched ESPs to monitor inbox placement or for companies that historically have been having email deliverability issues and would like to learn about the root cause and improve. Unlike ReturnPath, 250ok doesn't offer certification, but honestly, you don't need certification if you follow the Gmail/Microsoft/AOL/Yahoo bulk sender guidelines. I haven't seen a company which significantly improved their results with that certification and I've been working for one major ESP for 7 years. 250ok is a good diagnostic/monitoring tool but it is not a panacea for those who continue to violate sender guidelines due to poor list/content management.

If you have Marketo or Pardot and have emails that might be somewhat simple to slightly complex, without the budget for a developer, Knak is the right solution for you. If you have complex emails that require a lot of code or customization and have the in-house resources, Knak might not be the perfect solution

Pros

250ok

  • They provide a wide-ranging tool to view your email templates in many different email clients under different circumstances. We used this tool to identify specific issues we couldn't test that a small subset of users had complained about.
  • The Seedlist Optimizer Tool does the legwork for you to identify which ESPs are used the most and gives you a custom seed list for testing.
  • The Campaign Diagnostics report shows immediate feedback after sending on how your email is performing and where you can improve in the future.

Cons

250ok

  • Does not specifically identify which email addresses are spam traps
  • This is software as a service, so it's not managed and you need to have team members who can make adjustments to your email program
  • Would be nice if 250ok had a direct relationship with ISPs and could reach out on your behalf

Marketo has email templates and you can, of course, create your own - but Knak makes it so much easier to create templates that are nice looking and mobile-optimized.
