If you do not want to receive constant negative feedback from mailing lists, or regularly drop down in email services’ rankings due to negative bounce data, you should think about a quality email validation tools. This validation feature is also important for another reason: getting a positive balance from email marketing campaigns is impossible without minimizing email bounce rates. To minimize the bounce rate of email acceptance, you will have to apply “bulk” email validation before sending or resending emails. In doing so, it is desirable to conduct such verification on a regular basis, with a new company phase or expansion of an existing one.
This will require choosing one of the ways to verify the reality of the address. Both ways are realistic and easy for the organization. But, how and to whom should they be applied in practice? Let’s try to find out right now.
API from services or manual verification
There are two types of email verification:
– real-time validation using APIs provided by services such as Reply.io;
– checking an email list using free services and manually handling the addresses.
The first type of verification, as we have already clarified, is done automatically and almost immediately. To do this, services develop their own algorithms and search-and-reference databases. In any case – this is a very good solution because it immediately reduces the verification time and avoids unnecessary waste of time and resources for “empty” mailing addresses. Such email verifiers offer to work with lists or even entire databases of addresses, i.e. there is no need to enter each address separately.
Importing a list of email addresses from those currently in use in a mailing, reduces the time to verify the data for the mailing by 50-80%. And significantly increases the deliverability and relevancy parameters of user activity scores.
Manual verification with free resources is a bit longer and more complicated. In addition, it does not always work in instant request-response mode. An example of online services that work with a specific address is Email Checker or Hunter.
Alternatives from Google or Yahoo
Another way to do the verification is to use a mailing service like Google or Yahoo. When you enter a proposed email address for registration, the service automatically and very accurately evaluates the situation with the existing address. If it exists, the registration fails. This is a convenient way to check a small number of addresses or to clarify the address of a particular user.
