I've used most the email automation tools on the market and PersistIQ is the best IMO. It has a clean, intuitive interface that's easy to learn and use. They haven't complicated it with tons of useless features, and the core features like bounce detection, reply detection, OOO detection really work.
But the thing I love most is that it's not riddled with bugs like ToutApp, which we tried to use for about 6 months...I say try because with Tout you spend more time dealing with bugs and crashes than you do sending emails. Tout is definitely the worst option on the market...it's really horrible.
Not much to dislike, just a few recommendations for improvements.
-It would be nice to be able to group email templates into folders, instead of just having a long list of all templates.
-It's kind of hard to search for leads in the campaign screen and lead screen. A universal search tool that can be accessed from any page would be helpful. Also, the current search tools don't always work well...sometimes it's hard to find the person I'm looking for.
-The activity feed on the lead show view doesn't show emails and other activity. It would be nice to see all activity here.
- The lead page has a status of open and engaged, and the campaign page has four or five more / different statuses. This is confusing. In the lead index view I'd like to see the current campaign and current campaign status as the first two columns next to name. Right now these aren't even shown in this view.
-In the lead show view I'd like to see the current campaign and current campaign status....right now it just shows the campaign, not the status.
-A chrome extension that allowed me to click a button in gmail and automatically be taken to the associated contact record in Persist would be great. It would eliminate having to constantly manually search for people in Persist IQ.
