I have just try it out. Extremely slow for a big list..
Is it possible to after click validate, let it run at server, at the same time we can close the browser? (automated)
Or possible for multi thread in checking?
And I'm not sure whether the checking result is accurate. I have just done some testing by simply copy 12 emails that is Deleted, and email to them , after some time only receive 4 email delivery failure's notification.
Before that I have also try out some email verifier software, the result also not accurate. Every time I scan with those software, it give different result, sometimes the difference is quite big...
I now have a suggestion, if you really want to implement this in future release, you may consider let user to skip the type of email domain that they want to skip from script scan, since some domain don't seems to allow dns to check the email validity, thus script will assume it's not valid and delete all those email from a particular domain. Besides, you should put priority for deletion of non exist email, but not those email that when checking with script, it get smtp timeout etc...
Another suggestion, when click import user, we can tick the send welcome message to user. I always import leads, thus everytime will reach the sending process page.
Since it already have the resume sending script etc.. why not after the import done, show a status "SUCCESS IMPORT ALL SUBSCRIBER" first, then only show the sending welcome email status. It will reduce confusion and not letting us to always there to see the process until it finish sending. This is my comment
Dean, are you here?
