The platform is really easy for anyone with little or no experience in online marketing, it's very user-friendly - you can get up and running within minutes! I love that we have all of our emails integrated into one place so my team doesn't have multiple accounts which causes confusion when trying to track them down if something goes wrong (which happens far too often!).
We also receive notifications via email every time someone visits us from an external link like Facebook etc., this helps ensure people aren't missing out on key information about what they're signing up for as well as giving me important data regarding where referrals are coming through from. Occasionally there will be issues with performance but these tend to resolve themselves quickly once notified. There isn't anything major at present however would suggest using other services until more competition arises since their price point seems quite high compared to others currently available.
