Ontraport has changed the way I do business and I recommend it to all my clients (and let's face it - to anyone who will listen). The support is wonderful and the platform is powerful.
It's super powerful and has a lot of extensions via Zapier. The live chat contact support is AWESOME.
I usually deal with sending emails to a great amount of contacts. Writing an email is easy on Ontraport and scheduling features are great.
Really uneasy to build an emails with the builder. Fake drag and drop, which is really hard to use.
Email campaigns were difficult to execute. Just a long laundry list of problems.
The pricing tiers are rather odd as there's no middle ground.
