protected email account

[route66]

Hello BT community  I have an account for broadband which has recently switched to fibre on a new contract now EE.

We have BT email  and have several emails addresses within that  account.  Recently I have received regular messages from BT to tell me they have protected one particular email address as someone has tried to access it without my permission.  Its happening on a weekly basis and I have to use an access code and then change my password 

I use this particular email address to send out weekly emails to members of a bike club we belong to. We have around 300 members and I send the emails bcc in alphabetical groups.  To change the email account name would be a lot of work but having to change the password weekly is driving me mad. 

Does anyone have any suggestions please

Not much you can do really. Obviously somebody is either accidentally or deliberately trying to access that address.

As an aside, for that number of recipients I suggest you perhaps look into using something like Mail Chimp rather than using a flaky consumer email system.

If you are BCC your email address that you are sending from in the mailing list try removing it.
