Since 2001, Service Objects has provided real-time email validation services that verify and improve the deliverability and integrity of your email lists.

Service Objects’ email validation services perform over 50 verification tests to determine email address’ authenticity, accuracy, and deliverability. If desired, we can auto-correct common domain misspellings, syntax errors, and remove extraneous characters. By ensuring you are only sending to authentic and accurate email addresses, our service improves your sender reputation, protects your mail servers from being blacklisted and boosts your campaign's ROI.

Service Objects' DOTS Email Validation is now available for integration with Marketo.  Via Webhooks our Email Validation service can be added to your Marketo workflow.  By following the steps in our integration guide you will be up and running in moments.  Using the guide will allow you to map the results from the service to any of your updateable fields and allow you to do analysis on the results.  The Email Validation service will return a score amongst other data points that provides you with an estimate on the validity of an email address.

Score of 0 = Email is Good 
Score of 1 = Email is Probably Good 
Score of 2 = Unknown 
Score of 3 = Email is Probably Bad 
Score of 4 = Email is Bad

In addition to these scores and other data points we will also return warning descriptions and note descriptions that will give you more information about the email such as is the email a known greylister, is the email believed to be a spam trap or a known spammer, is the email known to be a bot.  We can add insight into whether we think the email is bogus, vulgar or garbage.  These and many more data points that we provide will help you make the best decisions and save you time.  If you are looking for more technical information and/or sample code, please visit our Developer Guide.
