Sendy can be installed in 3 ways.
1. Using Sendy 1-click hosting
2. Hiring a freelancer
3. Doing it yourself.
The first approach of using Sendybay is the easiest and the fastest. You will be able to quickly get up and running within minutes.
Alternatively, you can hire someone from Fiverr to install Sendy for you. THis might cost you $50-$100, depending on the reputation of the freelancer.
Installing Sendy yourself is discouraged unless you are somewhat tech savvy. Installing Sendy yourself requires setting up PHP, database and CRON at the minimum, which comes with it's own nuance.
