What is EOL (End of Life)?
When an email product is at its final stage of the life cycle, then this stage is referred to as EOL. This means that EOL brings a halt to the existence of an email product. There will no further improvement in the product as it cannot be actively maintained like before. Companies and individuals are advised to get rid of EOL email products as such products are prone to risks and can hamper the security of your system on a large scale. Hackers lookout for such products and try to attack them so as to get access to the whole system. Thus, companies send notifications by their business email hosting provider through email informing them about an EOL product for timely action.
