What is FakeSMTP?
FakeSMTP is a dummy SMTP server that is used primarily for testing and development purposes in email marketing. It catches emails sent out from your application and stores them locally, preventing them from reaching real recipients. This tool is extremely valuable for developers who need to test email functionalities without sending actual emails.
Cost-Effective: No need to pay for email delivery services during the testing phase.
Safe Environment: Prevents accidental spamming of real users during tests.
Debugging: Easily debug and inspect emails without affecting real traffic.
Integration Testing: Ensures that your email sending mechanisms are working as intended.
How Does FakeSMTP Work?
FakeSMTP acts as a local SMTP server. When your application sends an email, it is intercepted by FakeSMTP and stored locally. You can then review the emails to check for issues like formatting, subject lines, and delivery mechanisms. This process is crucial for resolving potential problems before a full-scale launch.
Setting Up FakeSMTP
Setting up FakeSMTP is relatively straightforward: Download the FakeSMTP jar file from the
official website.
Run the jar file using the command line: java -jar fakeSMTP.jar.
Configure your application to use localhost and the port FakeSMTP is running on (default is 2525).
After setting it up, all emails sent by your application will be captured and stored in the specified directory.
Common Use Cases
FakeSMTP is useful in various scenarios, including: Development: When building new features that involve email notifications.

While FakeSMTP is a powerful tool, it does have some limitations: Not for Production: It should never be used in a live environment.
Limited Analytics: It doesn't provide analytics or deliverability insights.
