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.

Sendblaster

Sendblaster is a great tool for any environment. It's particularly good in organizations that do not have a full featured CRM that manages bulk email marketing and communication. Even if an organization has a great CRM, Sendblaster is still great for those marketing or communication campaigns that go out to recipients who are not already in the CRM, custom groups, bulk sending that you want to keep separate from your other CRM(s), etc.

Sendblaster

  • Ultimate control over design of templates and messages. Sendblaster provides great templates, but you can also design your own from scratch, with total control.
  • Lots of options for sending your outgoing messages, including your organization's SMTP server, a third party's SMTP server, "direct" sending from your desktop, and many more configuration options.
  • Sendblaster is even easier than Microsoft Word for "merging" data into your outgoing messages.
  • Once you pay the affordable price for the Sendblaster software, there are no more ongoing subscription fees or volume-based per-message charges.

Cons

250ok

  • 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.

  • The user interface could be more polished. It's very easy to use, but the appearance of the user interface looks a little old fashioned for a desktop software. Of course recipients don't see that interface, so that is not very consequential.

Alternatives Considered

250ok

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.

Sendblaster

Sendblaster has all the features of these other alternatives, and its more flexible. Its a lot easier to develop custom messages/templates. There are a lot more sending configurations that are possible. There are no subscriptions fees with Sendblaster, unlike MailChimp and Constant Contact. I haven't found another solution that has all of the same features.

Return on Investment

250ok

  • Using 250ok, we were able to identify problem areas with specific email clients that we couldn't test manually (really old ones). Once solved, reactivated lapsed customers.

Sendblaster

  • Customer service was greatly improved because of Sendblaster. We were able to design our communication exactly the way we wanted to improve communication effectiveness.
  • Sendblaster helped our brand because email recipients have been very impressed by the polished visual appearance of our outgoing messages, consistent branding and use of logo, wordmark, and other identifiers, etc.
  • We saved a lot of money with Sendblaster. Our organization can send unlimited messages, and the Sendblaster software we paid for places no limit on messages sent. So, since there are no ongoing subscription fees or volume fees after paying for the the software, we saved a lot. Other "software as a service" options would have cost a minimum of $50 per month, and potentially a lot more than that for high-volume email communication.
