I'm an email developer for a European ESP and have been eyeballing this software that blows our own reporting and deliverability tools out of the water. I've been making my case for a POC with the software company but still needed a client to sign off for a trial with this new software. I wouldn't say it was tough to get them to sign because the benefits really are that much better, but I still had to make my case and now we have a running POC and possibly a reseller relationship with the software in mention. Being part of this is amazing because not only will it be great to offer something much better, but it will most likely also increase performance on our clients email marketing
That makes sense. I'm working at a small ESP and we are trying to decide what makes most sense. MailChimp are flat out saying that you should cut down on content otherwise the mails won't be tracked in those clients. I'm leaning towards the same statement. Maybe a combination of that and a toggle to switch the tracking up before the start body tag like Sam d'E Vallancey said.
