Do I need to have coding experience to use this editor?
No, thanks to Sidemail no‑code email editor, you can design emails without writing a single line of code. The editor provides building blocks for all common elements (text, buttons, images, lists, tables, charts, code blocks, etc.), and handles the complex HTML behind the scenes. You can create beautiful, responsive designs with just clicks – zero HTML/CSS knowledge needed.
How do Template Props work for dynamic content?
Template Props are simply variables that allow you to put dynamic data in your email templates. In the email editor, you define a variable by typing a name in curly braces. For example, in a password reset email template, you specify the URL of a button to {url} or {password_reset_url} depending on your preference. When sending the email template, you simply supply the URL (or whatever name you used) inside of templateProps object parameter. This lets you personalize each email with unique links, names, amounts, or any data you need. You can learn more in API docs.
Does Sidemail support dark mode in emails?
Yes – in fact, Sidemail was one of the first email providers to offer built‑in dark mode support. Every Sidemail template automatically includes a dark mode version with optimized colors and images. You just switch-on dark mode and upload two versions of your logo (for light and dark modes). We did extensive hands-on dark mode testing in all email clients, you can read more here.
Can I use my own brand and sending domain? Is it fully white‑label?
Yes, absolutely. When setting up your sending, add your own sending domain, so emails come from you@yourcompany.com. In the email editor, you customize the design with your logo, brand colors, font, etc. so email templates match your style.
How to get started?
First, create a Sidemail account (you get a free trial with full features). Inside the dashboard, create a project and add your sending domain. Then, customize the email template design – upload your company logo, customize colors and fonts, and enable dark mode if you wish. Next, import a premade email template or create one using the no‑code editor. Finally, it's time to send the email – to make this step easy, Sidemail provides you with copy-pastable code snippets for each email template directly in your Dashboard.
