"Absolute Nightmare!"
What do you like best about Reply?

Nothing- this program has created a compliance mess we are perpetually cleaning up and it just won't stop.

What do you dislike about Reply?

We tried out the trial version and had a few bumps with that, but no bid deal. Decided not to use Reply and moved on. Then one day, weeks later, totally out of the blue, hundreds of contacts received the exact same email from reply they had previously gotten. No one in my company had set it off, I am the only account manager for this tool and I hadn't logged in since I ended our trial. The email was responded to by angry prospects who told me they had already unsubscribed. The Reply team told me they needed my help in troubleshooting the issue- not something I have time to figure out for them. This has created a real compliance nightmare for us and it sent off an additional 90 emails today, after I contacted them about the problem. No one is even paying for this service, it's just firing off on its own.

What problems is Reply solving and how is that benefiting you?

None- it's creating problems, not solving them.
