When it comes to integrating a professional email sending service into your organization’s systems, you’ll typically choose between SMTP relay and a REST API. Both approaches work with KosherEmail — here’s how to decide which is right for you.
SMTP: The Universal Standard
SMTP (Simple Mail Transfer Protocol) is the original email sending protocol, and virtually every email software in existence supports it. If you’re using a CRM, synagogue management software, school administration platform, or any other application that sends email, it almost certainly supports SMTP configuration.
The advantages of SMTP are simplicity and universal compatibility. Simply update your outgoing mail server settings to point to KosherEmail’s SMTP servers, and your existing workflows continue unchanged — with dramatically improved deliverability.
SMTP is the right choice if you want to improve deliverability with minimal technical work, if you’re using off-the-shelf software with email functionality, or if your team doesn’t have developers to implement an API integration.
REST API: Maximum Control
A REST API gives you programmatic control over every aspect of email sending. You can manage lists, track engagement in real-time, segment your audience dynamically, and build sophisticated email automation — all through code.
The API approach is right for organizations with development resources who want to build custom email workflows, integrate email sending tightly with their website or app, or build sophisticated automation sequences.
Which Should You Choose?
For most synagogues and Jewish charitable organizations, SMTP integration is the right starting point. It provides dramatically better deliverability than your current setup with minimal technical work. Organizations with web development capabilities can layer in API integration for more sophisticated campaigns.
