Purchasing a B2B contact list, or directory, is legal and in some areas it may also be legal to send unsolicited emails. However, Esendex does not allow the use of these lists, and sending unsolicited emails is against our Terms of Service.

The law only protects companies selling B2B databases if it contains professional data and complies with local laws. However, it does not take into consideration the restrictions imposed by email providers and receiving platforms:

› Gmail recommends using only opt-in addresses
› Hotmail does not allow unsolicited commercial emails at all

What happens if you send unsolicited emails to B2B contacts at these providers?

It’s simple – you will get blacklisted, none of your emails will get through and your Esendex account may be suspended or terminated. Even if you have a dedicated IP, sending unsolicited emails cannot be allowed as it may lead to all our IPs being blocked.

We understand this is quite complicated and may make sending your business emails more difficult. But this is what is required to fight spam and provide better deliverability results for all our customers.
