Using spintax for variation

Create multiple versions of your emails automatically using spintax. This improves deliverability and helps your emails feel more natural.

What is Spintax?

Spintax (spin syntax) lets you write multiple variations of a word or phrase, and Outlio will randomly choose one for each email sent. This creates unique emails that are less likely to be flagged as spam.

How it works:

You write:

Leads might receive:

Hi Sarah

Hello John

Hey Mike

Spintax Syntax

Basic Format

{{option1 | option2 | option3}}

Wrap options in double curly braces, separated by pipe characters (|)

Examples

{{Hi | Hello | Hey}}→ Greetings

{{quick | brief | short}}→ Adjectives

{{chat | call | conversation}}→ Nouns

{{Best | Cheers | Thanks}}→ Sign-offs

Why Use Spintax?

Better Deliverability

Email providers flag identical emails sent in bulk. Spintax makes each email unique, reducing spam risk.

Natural Feel

Varied language makes emails feel more human and less like automated templates.

A/B Testing Built-in

Test different phrases and approaches within a single campaign without creating multiple versions.

Scale Safely

Send higher volumes without triggering spam filters that detect duplicate content.

Full Email Example

Subject: {{Quick question | Brief question | Reaching out}} about {{companyName}} {{Hi | Hello | Hey}} {{firstName}}, {{I noticed | I saw | I came across}} {{companyName}} {{is growing fast | has been expanding | is doing great things}} - {{impressive | congrats | love to see it}}! We {{help companies like yours | work with teams like yours | specialize in helping businesses}} {{achieve | accomplish | reach}} {{better results | their goals | success}} with [your offer]. {{Would you be open to | Are you interested in | How about}} a {{quick | brief | short}} {{chat | call | conversation}} {{this week | sometime soon}}? {{Best | Cheers | Thanks}}, [Your name]

This single template can generate thousands of unique email combinations!

Best Practices

Use 3-5 variations per spintax

Too few variations don't help much. Too many can make it hard to ensure quality across all combinations.

Keep variations similar in meaning

Each option should convey the same message. Don't mix formal and casual tones in the same spintax.

Vary subject lines too

Don't forget to add spintax to your subject lines. This is often where spam filters look first.

Preview before sending

Use the preview feature to see different combinations and make sure they all read naturally.

Combining with Variables

Spintax and variables work great together! Use variables for personalization (names, companies) and spintax for variety in your messaging. Example: {{Hi | Hello}} {{firstName}}

Tip: Variables like {{firstName}} have no pipes. Spintax like {{Hi | Hello}} always has pipes separating options.
