Creating Google Doc Templates for Mail Merge
Write {{tags}} in any Google Doc and SmartMerge AI handles the rest. Templates take under 5 minutes to create and work with any spreadsheet.
How Merge Tags Work
A merge tag is a placeholder wrapped in double curly braces: {{Column Header}}. The tag name must exactly match a column header in your Google Sheet. During a merge, SmartMerge AI replaces each tag with the row's value from that column.
Example template text:
Dear {{First Name}},
Thank you for your interest in {{Company}}. Your reference number is {{Ref ID}}.
If your spreadsheet has columns named "First Name", "Company", and "Ref ID", SmartMerge AI auto-matches them to the template tags. No manual configuration needed for exact matches.
Template Best Practices
Match tag names to column headers exactly
Tags are case-sensitive. If your column is "First Name", your tag must be {{First Name}} — not {{first name}} or {{FirstName}}. SmartCheck catches mismatches before the merge starts.
Format the tag, not the replacement
Apply formatting (bold, italic, font size, color) to the tag itself in your template. The merged content inherits whatever formatting the tag had. If {{Total Amount}} is bold and red, every replaced value will also be bold and red.
Use descriptive tag names
Tags like {{First Name}} and {{Due Date}} are self-documenting. Avoid abbreviations like {{fn}} or {{dd}} — they make templates harder to maintain and auto-mapping less reliable.
Keep one row = one document
Each row in your spreadsheet produces one merged document. Structure your data so that every row has complete information for one recipient. SmartCheck flags rows with missing values in tagged columns.
SmartCheck Pre-Flight Validation
SmartCheck runs automatically before every merge and catches problems before any documents are created. It validates tag syntax, checks for mismatched or missing tags, flags empty required fields, and alerts you to formatting issues. 92% of merge errors are caught by SmartCheck before they happen.
SmartCheck catches:
- Misspelled tag names
- Tags with no matching column
- Empty cells in tagged columns
- Broken curly braces
Common mistakes:
- {{first name}} vs {{First Name}}
- Single braces: {Name}
- Extra spaces: {{ Name }}
- Curly quotes instead of straight
How Auto-Mapping Works
When you select a template, SmartMerge AI scans every {{tag}} and compares them to your spreadsheet column headers. Exact matches are mapped automatically in under 60 seconds, regardless of how many tags your template has. Fuzzy matching suggests close matches for slightly different names.
For any tags that don't auto-match, the mapping step shows a dropdown with all available columns. Select the right column and the mapping is saved — SmartMerge remembers your mappings for next time.

Frequently Asked Questions
What is a merge tag?
A merge tag is a placeholder in your Google Doc template surrounded by double curly braces, like {{First Name}} or {{Company}}. During a merge, SmartMerge AI replaces each tag with the matching value from your Google Sheet. Tags are case-sensitive and must exactly match your spreadsheet column headers.
Does SmartMerge AI preserve my template formatting?
Yes. All formatting in your Google Doc template is preserved during the merge — bold, italic, font sizes, colors, tables, images, headers, and footers. The merged content inherits the formatting of the tag it replaces. If {{First Name}} is bold in your template, the replaced name will also be bold.
How many tags can I use in one template?
There is no hard limit on the number of merge tags. SmartMerge AI auto-detects every {{tag}} in your document and lists them in the mapping step. Users commonly use 5-20 tags per template, but templates with 50+ tags work as expected. SmartCheck validates all tags regardless of count.
Can I reuse the same template for different spreadsheets?
Yes. Templates are standard Google Docs stored in your Drive. Use the same template with any spreadsheet — just map the columns to tags each time. SmartMerge AI remembers the last mapping for each spreadsheet-template pair, so repeat merges only take seconds to set up.
