250ok Inbox

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.

Knak.

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

Cons

  • Documentation website could use some improvement (i.e. Search on the API Guide page, videos in the User Guide).
  • Can't copy/paste certain things from the UI (i.e. IP ranges).
  • Doesn't integrate directly with some ESPs although it's easy to just use new seed lists.

  • Sometimes there are issues with buggy code
  • Updates sometimes will break emails

Alternatives Considered

We use both 250ok and ReturnPath in the company (because we're an ESP) and both have their own pros and cons. Return Path uses panel data while 250ok uses recipients' engagement date for reporting. Both ways have pros and cons but you can't say one is better than the other. They're just different. ReturnPath also offers certification which (I have to be honest) is not as relevant anymore as there is only one way to fix deliverability issues nowadays - by following bulk sender guidelines posted by Gmail, Yahoo, AOL, Microsoft, and other ISPs. ReturnPath has a better documentation website while 250ok could use some refinement. With 250ok you can choose the tools you need and build your own package and save money. With ReturnPath - not so much. 250ok also has partners across the globe while ReturnPath mostly promotes its own services and consultants.

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.
