Hi @Saad ,
I recently worked on setting up the AWS SES service to replace the default SMTP service in ODK Central. Since I noticed there isn’t much information available online about this configuration, I decided to share my experience and create a guide to help others.
You can find the detailed guide here:
Configuring ODK Central with Amazon SES for SMTP Messaging
I hope you find it helpful! Feel free to reach out if you have any questions or need further assistance.
