Every entrepreneur faces one important problem at least once in his life – expanding business is impossible without using new information for e-marketing. But gradually accumulates a critical mass of addresses in the mailing lists, to which there is either no response, or they are persistently “lost” in the vastness of the delivery service. You can find out what’s really going on by using email validation tools with mass address verification. Services such as Reply.io do this instantly and report on the entire list of data. To check how important this is and how many of the seemingly trusted addresses may in fact be invalid, you can just do a simple manual random check. We will tell you how to do it right now.

Free service, simple solution and a little bit of manual work

Make a list of 10-15 addresses that are critical to double-check for reality. That should be enough to get you started. While such a cross-section probably won’t be relevant enough, it will at least show how effective you are at communicating with your most important partners and customers. For example, you can use Hunter. Here you can check “by the piece” in free mode for not more than 50 addresses in one month. Another similar service is Anymail Finder. It offers 90 free addresses, but only once.

All such or similar services are based on checking by pasting or typing the address into the search bar. In this way you can ascertain:

– syntax errors;

– invalidity of the address;

– invalidity of the address.

As we see the main disadvantage of such solutions – limited resources and capabilities. In addition, services that work as automated verification systems also offer many other service functions. In addition to email verification, such complexes usually also offer:

– tools with the functions of searching for potential clients;

– work with relevant email databases;

– searching through social networking accounts;

– search for information from conventional search engines.

To summarize: various free systems can offer a truncated but sufficient verification method, though in terms of functionality. This system will help in unique cases or for selective verification of individual list segments. It will require mostly manual work and time to implement verification. Automated methods are much more convenient and guarantee quick results, as well as regular updates of the addresses in case rechecking is necessary.
