We get a lot of enquiries on helpdesk from our customer about whether we do email list cleaning.
The answer is "NO". We as ESP are more focused on getting your emails delivered without problems. It is beyond our scope to do the email list cleaning.
However, we can certainly make some recommendations that can help you clean your lists. After all, we also want our customers to import good and fresh data into our system as it creates less problems for us.
As a clear policy, I want to be loud about the fact that we don't and will not tolerate Spam Traps at any cost. It not only affects our reputation as ESP, it also hurts email deliverability of thousands of BulkResponse customers who have clean double opt-in lists and follow good mailing practices. So NO Spam Traps allowed here. Period.
There for, it is...
