FAQ

Do I need to know HTML to create emails?

No, you can create all emails in the user-friendly and easy-to-use editor. So, you don’t need to know HTML at all.

I already have an email template.
Can I use it?

Yes, you can import a template from a ZIP archive and edit it in Letteros.

Can I send emails directly in Letteros?

No, the email needs to be uploaded to any platform you are used to.

What ESP platforms can I use for mass
email sendings?

SendPulse, GetResponse, Mailchimp and other popular platforms.

How to check email responsiveness?

Check out previews on desktop and mobile.

How do you know that the email looks great and is not cut on different mailers?

Send a test email and test it on 9 email clients.

How many links should be in an email?

Many links will only confuse the reader and will not bring the desired result. Add multiple links, but keep one main focus. Better as a button.

What is the best email size to avoid spam?

Messages smaller than 100 KB successfully pass the anti-spam check. There may be problems with increasing the size: one or more spam filters do not allow the message to enter the Inbox. To do this, we built code and image compression tools into the platform.
