Cleaning Your Email List

 

We have spoken on several occasions about the importance of keeping your email lists clean. People change jobs so often most of your list can be outdated in six months while statistics show that 30% of your list is completely unusable within a year.

Luckily, there are tools and data appending agencies which can help you check if the emails on your contact list will go to the right person. 

1. DataValidation

DataValidation is deemed best email cleaning tool by marketing and sales professionals. All you have to do is upload your list of contacts and it can tell you not only whether the email is correct or not, but even whether it’s been used recently. They have excellent user experience and they even provide you with a quality score explaining what percentage of your list is usable. Unfortunately, they are one of the most expensive tools as well. For 10k emails, you will have to pay $50, while 100k emails will cost $300.

2. EmailListVerify

EmailListVerify can provide you with information about who are the main complainers on your list and whether you got caught in any spam traps. You can either upload your CVS file or connect it to your MailChimp account. Processing may take somewhere between 30 to 120 minutes depending on the size of your list. You purchase credits which you spend in the pay-as-you-go manner. If you have up to 100 contacts that need to be checked, you can use it for free, while uploading 10K emails will cost you $24 and 100K emails will cost you $169.
