One of my clients is a registered charity working in a rural area. Their provider is Zen Internet and they have a policy of allowing just 5 bounce backs for users within an hour to deter spamming.
Their address book is quite large and despite attempting to clean up their address book everytime they send out a bulk email they get blocked by zen with the following message.
"Domain xxxxxxx.org has exceeded the max defers and failures per hour (5/5
(71%)) allowed. Message discarded."
A limit of 5 is very low but thats Zens policy and I an see why providers are starting to do this. Apart from constantly validating addresses which is difficult is there another way around this? Zen mentioned Mail Chimp but I have no idea how this works and their website doesnt really tell you much. I also wondered if it would be possible to set up a Gmail account with an alias to the main sender at my client just for sending out these emails.
As said its a charity not a buiness working with people across a wide rural community.
