So your team has never really been capturing email addresses, or the person who was doing the data capturing was a student, and half the time they were either hungover or didn’t understand the difference between their elbow or their “digestive tract”.
You are not alone.
We get this comment in meetings and emails all the time. There is hope, and you can do something about it.
Lets split the problem up into different parts, and let’s find solutions to each element.
Our first split is past and present.
Can’t do anything about it? Or, can you?
If you have all the hard copies of the opt-ins, you could look at doing a recapture of the data, but think about how much time has passed since those people got something from you?
The cost of doing this might be a bit high for the reward you could get.
Unless a strong business case exists, it’s usually, a “let the past be the past.”
Ok, so what about the data we do have, can we validate it?
We have a list validation service, where we check a few factors about the mailbox. We return a rich set of metrics on each email.
Here is a snippet of the results (a little technical, but worth a skim read)
The verification result:
And the reason:
invalid_email - Specified email is not a valid email address syntax
invalid_domain - Domain for email does not exist
rejected_email - Email address was rejected by the SMTP server, email address does not exist
accepted_email - The SMTP server accepted email address
low_quality - Email address has quality issues that may make it a risky or low-value address
low_deliverability - Email address appears to be deliverable, but deliverability cannot be guaranteed
no_connect - Could not connect to SMTP server
timeout - SMTP session timed out
invalid_smtp - SMTP server returned an unexpected/invalid response
unavailable_smtp - SMTP server was unavailable to process our request
unexpected_error - An unexpected error has occurred
role true | false - true if the email address is a role address ([email protected], [email protected], etc.)
free true | false - true if the email address uses a free email service like gmail.com or yahoo.com.
disposable true | false - true if the email address uses a disposable domain like trashmail.com or mailinator.com.
accept_all true | false - true if the email was accepted, but the domain appears to accept all emails addressed to that domain.
did_you_mean null | string - Returns a suggested email if a possible spelling error was detected. ([email protected] -> [email protected])
quality float - A quality score of the provided email address ranging between 0 (no quality) and 1 (perfect quality). More information on the Quality Scores are listed below
email string - Returns a normalised version of the provided email address. ([email protected] -> [email protected])
user string - The user (a.k.a local part) of the provided email address. ([email protected] -> bob)
domain string - The domain of the provided email address. ([email protected] -> example.com)
success true | false - true if the API request was successful (i.e., no authentication or unexpected errors occurred)
We then remove the addresses that don’t work anymore, and fix the spelling errors.
We can use the above metrics to further target our communication to just the best of the best.
Quality Score 1.00-0.55: Good 0.54-0.20: Fair 0.19-0.00: Poor
Quality Score 1.00-0.70: Good 0.69-0.40: Fair 0.39-0.00: Poor
Great, we now have a higher level of confidence that the list you have is of people that exist.
Now let’s look at the future segment of our problem.
What are we going to change about the way we capture data?
Have a look at these touch points in your company and see if you can improve on the operations or systems to help capture a person’s details:
How you go about changing or implementing these things is generally up to each company.
The third thing is to look at how rich the data is. How much do you know about the person on the database?
We have a data enrichment service where we can find a lot of other public domain knowledge about a person based on their email address.
We then follow these steps for you:
Here is my report, all taken from just my email address [email protected]
It’s excellent having just one person details, though we need this at scale so we can segment and communicate.
The crucial part of the 44:1 ratio is that 77% of that is made up of automated and targetted communication. Data enrichment helps you do this.
Here are some screenshots of the types of data you can expect to find out about your database by using our enrichment services:
Here is an incomplete list of topics you can expect to see:
Let’s take the data a level lower, and this is the detail that emerges.
So to recap, yes we can do something.
Feel free to drop me an email to chat more about this. Always happy to help.
