Templates and Sending
Common questions about building message templates, editors, and sending.
What Is the Character Limit for SMS Messages?
Standard SMS messages using GSM-7 encoding support 160 characters per segment. Messages using special characters or emoji (UCS-2 encoding) support 70 characters per segment. Messages exceeding one segment are split into multiple segments, each counting as a separate message. See SMS Templates for more detail.
How Do Variables Work in Templates?
Variables are dynamic placeholders mapped from your CSV columns. When the campaign is sent, each variable is replaced with the actual value from that recipient's row. If a value is missing, the variable placeholder appears as-is in the delivered message (e.g. {{first_name}}).
What Is the Difference Between the Visual and Code Email Editors?
The Design Editor is a block-based builder that uses a hover-and-click interaction model, ideal for users who want to create emails without writing HTML. The Code Editor is a full HTML editor with syntax highlighting, ideal for users who need precise control over markup and styling. See Choosing an Email Editor for a detailed comparison, or go directly to the Design Editor Guide or Code Editor Guide.
Can I Switch Between Visual and Code Editors?
Yes, but switching clears the email body content. Sender settings, variables, test data, and attachments are preserved. You are prompted to confirm before the switch happens.
What Is the Attachment Size Limit for Emails?
The total combined size of all attachments per email template is 20 MB. There is no fixed limit on the number of individual files, as long as the total stays under 20 MB. See Attachments for details.
How Do I Send a Test Email?
In the email template editor, click Send Test Email. You can send to up to 10 recipients at once. The test email uses your current sender settings and test data values.
Can I Import or Export Email Templates?
Yes. Templates can be exported to a file and imported back later. Each editor type uses its own file format (.or_design_template or .or_code_template), and you can only import a file that matches the editor you are currently using. See Importing and Exporting Templates for the full guide.
