Sendy is one of the DIY Email Marketing systems (self-installing and self-deploying), which is quite popular in the world thanks to its low price and diverse features.
Sendy system uses PHP code, MySQL database, to use, you need to upload to Hosting or use VPS and register 1 SMTP Server. It is best to use VPS to operate stably because Hosting is often limited, IP gets blacklist.
The cost of using this Email Marketing system includes the cost of buying a license (buy once), Hosting or VPS on a monthly basis and the cost of SMTP Server.
The usual price to buy a license to use Sendy is $59/domain (no subdomain limit). On the occasion of the birthday, Sendy is discounting $12 to just $47.
This is a license forever, all future updates are free, except for a few major upgrades. The main domain can be changed freely.
Sendy rarely promotes, maybe 1, 2 times a year, if you are using Email Marketing, you should take advantage of this cheap sale.
Promotion lasts until the end of this Friday.
