Formatting Rules for Outreach Content

Email providers and LinkedIn track formatting patterns to determine whether a message appears natural, promotional, or automated. Formatting that looks unusual—such as bold text, bright colors, scripts, or hidden styling—can cause messages to land in spam or trigger platform restrictions.

To protect deliverability, the Outreach Agent removes unsupported formatting automatically. Messages are written in clean, plain-text style so they are professional, readable, and inbox-friendly. No user action is required.

The Agent permits only standard text elements commonly used in human-written outreach. These elements appear normally in messages:

This ensures messages look natural while still allowing links to appear as readable URLs.

Plain sentences and paragraphs
“Hi Jane, I wanted to reach out with an idea for how we could help your team scale faster.”

Plain URLs
“Learn more at callsine.com”

Simple paragraph structure
“We’ve helped similar SaaS teams book more demos.
Would you be open to a short call?”

Before sending, the Agent removes formatting that email providers often associate with spam or mass-marketing automation. This includes:

If a message attempts to generate unsupported formatting, the Agent strips it out before delivery.

Plain-text formatting improves inbox placement and helps messages appear natural on both email and LinkedIn. By filtering unsupported styling, the Agent protects deliverability, reduces the chance of being flagged as automated, and ensures outreach remains professional.
