Projects help you be more organized. Each project has its own template design, API keys, and settings. You can change the project name later.
Both of these you can change later in project settings or overwrite when making a send email API request.
Pick a background and highlight colors which suit your brand. You can change these preferences later in Templates > Design (click "Tweak design" button). If you'll be sending custom html or plain-text emails this won't have any affect on them.
Check your inbox, Sidemail just sent you a verification email. It sometimes tends to go into the junk (spam) folder, check there if necessary. Click the verification link inside the email. It'll redirect you back to your Sidemail dashboard.
Note: Please, excuse a look of this email. As you probably know, behind the scenes Sidemail is using battle-tested AWS SES for reliable delivery until we migrate to our own mailing servers. There’re a few constraints due to the limited control over the AWS SES. This email design is one of them.
Sidemail automatically adds frequently used emails as templates into your project. You can find them in the Templates section of your project. Learn more about templates and working with them.
