Sendy features and specs

  • Cost-effective
    Sendy provides a cost-effective solution for email marketing by allowing users to send emails via Amazon SES, which is significantly cheaper than other email marketing services.
  • Self-hosted
    Since Sendy is a self-hosted application, users have full control over their data and server environment, providing better privacy and customizability.
  • High Deliverability
    By leveraging Amazon SES, Sendy offers high deliverability rates, ensuring that emails land in recipients' inboxes rather than spam folders.
  • One-time Payment
    Sendy requires a one-time payment for the license, making it a more affordable option in the long run compared to recurring subscription models.
  • Rich Features
    Sendy includes many features such as campaign tracking, list segmentation, autoresponders, and integration with other applications, making it a comprehensive email marketing solution.

Possible disadvantages of Sendy

  • Technical Setup
    As a self-hosted application, setting up Sendy requires some technical knowledge and can be challenging for users who are not familiar with server management and configuration.
  • Limited Integrations
    Unlike cloud-based email marketing services, Sendy offers fewer integrations with other third-party applications and services, which may limit its usability for some users.
  • No Built-in Customer Support
    Sendy does not offer dedicated customer support; users must rely on the community forum and documentation for troubleshooting and assistance.
  • Dependence on AWS
    Sendy specifically relies on Amazon SES for email delivery. If AWS services experience downtime or issues, Sendy's email delivery could be affected.
  • Initial Cost
    While Sendy is generally cost-effective in the long term, the initial license purchase might be a barrier for individuals or small businesses with very limited budgets.

Any good Mailchimp alternatives?
Separately, been keeping a list of Mailchimp alternatives. Sendfox works pretty well, and I plan to try out Sendy sometime soon.
7 Cheaper Mailchimp Alternatives to Consider in 2019
Once you install Sendy on your own server, youโ€™ll connect to Amazon SES to send the actual emails, which costs just $0.0001 per email (maybe an easier way to look at that is $1 per 10,000 emails). Plus, thereโ€™s no cost for more subscribers, which makes it a great option for big lists.
