Spintax stands for spinning syntax. It is a formatting method that helps you create many variations of the same cold email automatically.

If you send the exact same message to hundreds or thousands of people, inbox providers like Google and Microsoft can detect it as bulk mail and reduce deliverability. Spintax makes each email look slightly different, so it feels more like a human sending messages one by one.

Inbox providers look for repeated patterns.

Spintax tells your sending tool to randomly choose one option from a list.

It uses:

Format

{Option one|Option two|Option three}

Example

{Hi|Hello|Hey}

Each email send will randomly pick one option.

Swaps individual words.

Example

I {wanted|needed} to {ask|check} you about this.

Swaps full sentences. More powerful because it changes structure.

Example

{I noticed you are hiring.|I saw your job post.|Congrats on the open role.}

Spintax inside spintax. This creates a very large number of variations.

Example

{{Hi|Hey} there|{Hello|Hi} {{first_name}}}

The goal is uniqueness.

This helps reduce “content fingerprinting” where filters detect repeated text patterns at scale.

{Hi|Hello|Hey} {{first_name}},

{I noticed|I saw} you are {running|using} {ads|paid ads} for your business.

{We help|Our platform helps} teams {reduce|lower} costs using AI.

{Open to a quick chat?|Worth exploring?|Interested?}
