Description

SMTP Senpai, offered by MailSenpai, serves as the SMTP relay for emails generated by your applications, websites, and tools, handling everything from sign-ups and password resets to order confirmations, notifications, and contact forms. You can connect using standard SMTP (port 2525 or 587 with STARTTLS), a REST API that provides JSON responses, or a dedicated form endpoint suitable for web forms, even on static sites. All outgoing emails are DKIM-signed using your own domain, for which we supply the necessary DNS records and verify them on your behalf. Automatically, we suppress bounced addresses, maintain a 90-day log of all sent emails, and provide you with a comprehensive weekly report. Rather than suspending your account upon exceeding a certain threshold, we issue a warning and guide you on what needs to be addressed. Our servers and data operations are based in the EU, and we offer support in both Italian and English through tickets and email. Try us out with a 14-day free trial that requires a card for registration (you can cancel anytime), and then continue with plans starting at €12.90 per month for up to 10,000 emails on an annual subscription. This service ensures reliable email delivery while offering flexibility and support for your communication needs.

Description

SendLit is a versatile open-source email marketing tool designed for newsletter teams, individual creators, small enterprises, and software platforms that seek to manage email communications or integrate sending functionalities directly into their products. This platform offers features such as visually appealing broadcasts, audience segmentation, automated email sequences, and transactional messaging through a REST API, allowing for a comprehensive email marketing experience. Users can easily link up Amazon SES or various SMTP providers, oversee contact lists and email templates, and utilize suppression lists, tracking capabilities, and one-click unsubscribe options. The service is available in both free and paid tiered plans that are determined by the monthly email volume, and it also supports self-hosting via Docker Compose. For developers, a TypeScript SDK, an MCP server, a team-provisioning API, and an embeddable React editor facilitate seamless integrations and automated workflows. With no limitations on contacts for hosted plans and separate charges for email providers, SendLit ensures flexibility and scalability for its users. Currently, the platform is being developed without external funding, and features like bounce handling and support for multiple user accounts are anticipated in future updates. As it continues to evolve, SendLit aims to enhance its offerings while maintaining user-centric innovations.
