DRIP is the one and only service that offer a 100% FREE account and get to experience a complete ESP service account, on steroids, and I mean it ! You get to use things like automated workflows, lead scoring , tons of integration, analytics etc.
I dislike that you only get 100 contacts free. :-)
It does not offer landing pages or social media integration but there is ways around it. But we may see these features very soon.
I'd recommend start with free DRIP account is limited to 100 leads– which is more than enough to get you started. But if you have more its okay, just setup a trial period and move along, it will gives you time to learn and get to discover its full capbilities/great features on the free version before start paying to increase and build your audience. Plus side, it gives you time to setup multiple campaigns so you can try, test and improve.
If you're serious and want to take your email marketing to the next level, then you should seriously consider Drip. It offers you many blueprint options out-of-the-box which is (a bonus) great to get you up-and-running in less than an hour. Drip offers solid tutorials, docs, videos and it is totally versatile, flexible and not expensive for what you get.
You only need to plan, name your campaigns, and select one of the pre-design email templates.
Drip’s gets you (thinking) going even further with its segmenting capabilities allowing you to elaborate and/or craft out niche groups of people if you fancy offering a promo or limited time offer.
I would highly recommend Drip if you're selling consulting services, e-products and/or courses then do not hesitate as Drip offers a super intuitive visual builder allowing you to create marketing automations with just a few clicks - seriously is that simple. Add a superbe marketing automation solution to your business and expect a boost in your sales and conversions.
Also, Leadpages merge/acquire DRIP recently, so this also tells us that Drip is going to be here for the long haul.
