Hi,

You can use SMTP from other email service provider. Here's a couple of other alternatives:

1. Sendgrid http://www.sendgrid.com/
2. Mailgun http://www.mailgun.com/
3. Postmark https://postmarkapp.com/
4. SocketLabs http://www.socketlabs.com/
5. Mailjet http://www.mailjet.com/

Please note that as Sendy is designed for Amazon SES, if you use other email service providers, bounces and complaints will not be registered. But these services may let you download emails that bounced or complained which you can then import into Sendy to mass delete or mass unsubscribed.

Here's how to use other email service providers with Sendy via SMTP:

1. Remove your Amazon SES credentials from Settings
2. Edit your desired brand, then enter the SMTP credentials

Your emails will be sent via SMTP with the settings you've set.

Best regards,
Ben
