Mailrith vs. Sendy
Choose Mailrith if you want to connect Amazon SES or another email delivery service without maintaining the marketing application, server, database, backups, updates, or security. Choose Sendy if your team can run a self-hosted application and prefers a one-time software license.
Pricing Model
Compare How Each Product Charges
Mailrith is a hosted subscription with unlimited Subscribers on public paid plans. The email delivery service charges separately. Sendy uses a one-time software license, and the customer pays for hosting, maintenance, and email delivery, commonly through Amazon SES. Sendy's license can keep software cost low, but you should also count installation, updates, backups, monitoring, security, troubleshooting, and staff time.
