Spintax allows you to create multiple variations of an email or message from a single template. Instead of sending identical wording to every contact, you can define alternative words or phrases that Salesforge can use to generate different versions of your message.
When used correctly, spintax helps make outreach more varied and natural while preserving the original meaning of your message. Salesforge supports manual spintax and Auto Spintax in Multichannel Sequences, with additional tools to preview message variations and identify syntax errors before launching a sequence.
This article explains how spintax works, how to use it, how to combine it with personalization variables, and how to troubleshoot common issues.
Spintax is a formatting method that defines alternative words or phrases within curly braces, separated by vertical bars (|).
For example:
{{Hi|Hello|Hey}} {{first_name}},
This defines three possible greetings:
Hi Alex,
Hello Alex,
Hey Alex,
The system selects a variation when generating the message. The exact wording may differ between contacts or messages, depending on the spintax configuration and how the message is processed.
Spintax can be used for individual words, complete phrases, and longer parts of a message.
Alternative greetings
{{Hi|Hello|Hey}} {{first_name}},
Alternative introductions
I {{noticed|saw|came across}} your company while researching {{the industry|your market|companies in this space}}.
Alternative meeting requests
Would you be {{open to|available for|interested in}} a quick conversation next week?
Alternative closing lines
{{Best regards|Thanks|All the best}},
These examples illustrate how you can create variations while keeping the message's overall intent consistent.
Correct syntax is essential for spintax to work as expected.
A standard spintax expression follows this structure:
{{Option 1|Option 2|Option 3}}
The expression contains:
An opening double curly brace: {{
Two or more alternative options
A vertical bar (|) between each option
A closing double curly brace: }}
Each option represents an alternative that can be used in the final message.
1. Use the correct braces
Use double curly braces to define the alternatives:
Correct: {{Hi|Hello}}
Incorrect: {Hi|Hello}
2. Separate alternatives with vertical bars
Correct: {{quick call|short meeting|brief conversation}}
Incorrect: {{quick call, short meeting, brief conversation}}
3. Close every spintax expression
Correct: I {{noticed|saw}} your recent announcement.
Incorrect: I {{noticed|saw your recent announcement.
4. Keep each variation grammatically correct
Each alternative should fit naturally into the surrounding sentence.
For example:
We {{help|support|work with}} B2B sales teams.
This is more consistent than combining alternatives that require different sentence structures.
5. Avoid changing the original meaning
Spintax should create natural wording variations without introducing inaccurate claims, contradictory information, or misleading statements.
You can write spintax directly in the message content when building a sequence.
Open Salesforge and navigate to your Multichannel Sequences.
Create a new sequence or open an existing one.
Select the email or LinkedIn message step you want to edit.
Add spintax expressions to the message wherever alternative wording is appropriate.
Review the message to ensure every expression uses valid syntax.
Preview the message variations before launching the sequence.
Launch the sequence after resolving any blocking content issues.
Manual spintax gives you control over exactly which alternatives are available and how they fit into your message.
Auto Spintax helps generate wording variations without requiring you to write every spintax expression manually.
Salesforge introduced Auto Spintax for Multichannel Sequences to make message variation easier across supported outreach actions.
Open the Multichannel Sequence Builder.
Select the message step you want to improve.
Open the Auto Spintax feature.
Generate the suggested variations.
Review the generated content and make any necessary changes.
Apply the variations once you are satisfied with their quality.
Preview the resulting messages and check for validation issues before launching.
The interface may vary depending on the current sequence builder version.
Salesforge introduced improvements to Auto Spintax on June 16, 2026, focusing on message quality and control.
These improvements include:
More natural and grammatically correct wording.
Better preservation of the original message's intent.
No intentional introduction of spam words into generated variations.
Lower spam scores in most generated outputs.
An updated review-and-apply workflow that lets users inspect suggestions before applying them.
Auto Spintax is designed to help produce better variations, but generated content should still be reviewed before sending.
Spintax and personalization variables serve different purposes and can be combined in the same message.
Spintax provides alternative wording.
Personalization variables insert contact-specific information, such as a first name or company name.
For example:
{{Hi|Hello|Hey}} {{first_name}}, I {{noticed|saw}} that {{company_name}} is growing in your market.
Depending on the available contact data and the variations selected, the final message could look like:
Hi Alex, I noticed that Acme is growing in your market.
Hello Alex, I saw that Acme is growing in your market.
Always use the exact variable names supported by the Salesforge variable picker. The examples above are illustrative; available variable names may differ depending on your setup.
Incorrect or unsupported variables can cause personalization problems and may be flagged by the sequence builder's validation checks.
Salesforge supports message and email previews in the Multichannel Sequence Builder. These previews help you review how variables and spintax will appear in the final message.
The preview feature can show up to five examples for each supported message node.
Open your Multichannel Sequence.
Select the email or LinkedIn message step you want to inspect.
Open the message preview.
Review the displayed examples.
Check that the spintax variations sound natural and preserve the intended meaning.
Confirm that personalization variables render correctly.
Update the message if any variation is awkward, inaccurate, or incomplete.
Previews are useful for checking message quality before launch. However, a preview showing several valid examples does not guarantee that every possible variation will be suitable.
On October 19, 2026, Salesforge introduced pre-launch checks for Multichannel Sequences.
These checks help identify configuration and content problems before a sequence goes live.
For message content, the builder can flag:
Broken spintax expressions.
Incorrect personalization variables.
Empty email messages.
Missing InMail subjects.
InMail messages exceeding 2,000 characters.
When an issue is detected, Salesforge highlights the relevant step and A/B variant and provides a tooltip explaining the problem.
Click Launch in the sequence builder.
Review the validation results displayed across the Builder, Contacts, and Senders tabs.
Open the affected message step.
Read the validation message to identify the issue.
Correct the spintax syntax or variable.
Launch the sequence again after resolving any blocking issues.
Blocking issues prevent the sequence from launching until they are fixed. Warnings may allow the sequence to launch, depending on the issue.
Salesforge also reruns checks when you edit a running sequence, helping identify newly introduced issues.
Spintax support depends on the product and message type.
Auto Spintax was introduced for:
Email messages.
LinkedIn messages.
LinkedIn connection request notes.
The Multichannel Sequence Builder also supports previews and validation for message content.
Warmforge supports spintax and personalization variables in email signatures and placement tests. This allows supported test messages to be processed with dynamic wording and variables.
For example:
{{Hello|Hi}}, I am {{sender_first_name}}.
The rendered message may use one greeting and the corresponding sender name.
Warmforge's support for spintax in signatures and placement tests is separate from the sequence-building workflow in Salesforge.
Every alternative should sound like something a person would actually write. Avoid adding variations simply to increase the number of possible combinations.
Check that each alternative fits the sentence structure around it. If an option requires a different sentence structure, consider rewriting the entire phrase.
Spintax should change how a message is expressed, not the facts or promises it contains.
Auto Spintax improves variation quality, but it does not remove the need for human review. Inspect generated alternatives before applying them.
Use supported variable names and make sure all spintax expressions are correctly opened and closed.
Use message previews and pre-launch validation to identify errors before your sequence starts sending.
Spintax can increase wording variation, but it does not guarantee inbox placement or prevent spam filtering. Deliverability also depends on sender reputation, recipient engagement, sending practices, message content, and other factors.
Avoid using spintax to disguise repetitive, misleading, or irrelevant outreach.
Possible cause: The expression may use incorrect braces, contain missing separators, or be malformed.
What to do:
Check the opening and closing braces.
Confirm that alternatives are separated with vertical bars.
Review the validation tooltip in the sequence builder.
Preview the corrected message again.
Possible cause: Salesforge has detected a blocking issue in the sequence, which may involve spintax, variables, missing senders, or other content requirements.
What to do:
Review the errors shown after clicking Launch.
Open the affected step or A/B variant.
Correct the reported issue.
Run the validation checks again.
Possible cause: The variable name may be unsupported or incorrectly formatted.
What to do:
Insert the variable using the available personalization picker.
Verify that the required contact field contains data.
Preview the message to confirm that the variable renders as expected.
Possible cause: Some alternatives may not fit the surrounding sentence or the intended tone.
What to do:
Review the generated suggestions before applying them.
Remove unsuitable alternatives.
Rewrite the original sentence to make variations easier to generate.
Preview the updated message again.
Possible cause: A preview displays examples, not necessarily every possible variation. Other issues may also arise from missing contact data, message context, or the surrounding content.
What to do:
Review all visible preview examples.
Check the underlying spintax expressions and variables.
Verify that every alternative preserves the intended meaning.
Resolve any additional validation warnings or errors.
Does spintax guarantee better deliverability?
No. Spintax creates wording variations, but it cannot guarantee inbox placement or prevent spam filtering.
Does Auto Spintax intentionally add spam words?
Our Auto Spintax improvements specifically removed the intentional introduction of spam words into generated variations. Nevertheless, generated content should still be reviewed.
Can I use spintax with personalization variables?
Yes, supported spintax expressions can be combined with personalization variables. Make sure you use valid variable names and preview the rendered message.
Can I check spintax before launching a sequence?
Yes. Salesforge's pre-launch checks flag broken spintax and incorrect variables, identifying the affected step and A/B variant.
Can I use spintax in Warmforge?
Yes. Warmforge supports spintax and variables in email signatures and placement tests.
Does a successful validation mean every variation is perfect?
No. Validation helps detect supported syntax and configuration issues. You should still review message previews and check that the wording is natural, accurate, and appropriate.
Spintax helps you create multiple versions of an outreach message without maintaining a separate template for every variation. Salesforge provides manual spintax, Auto Spintax, message previews, and pre-launch validation to help you build and review dynamic content.
For the best results, use valid syntax, choose natural alternatives, verify personalization variables, preview your messages, and resolve validation errors before launching. Treat spintax as a content variation tool rather than a guarantee of deliverability.
