What to Look for When Choosing an Outreach Tool

Four critical evaluation criteria that protect your deliverability and budget.

Custom Tracking Domains

Using shared tracking links gets your emails flagged as spam. Ensure your tracking links use your own subdomain (e.g., track.yourdomain.com).

Zero Forced Watermarks

Prospects immediately spot free trackers like 'Sent with Mailtrack' and lose trust. OutSends is 100% white-label.

Frequently Asked Questions

Answers to common questions about choosing the right software.

Why is a custom tracking domain important?

When email service providers see shared tracking URLs in cold emails, they frequently route them to spam. Using your own custom tracking domain keeps your domain reputation isolated and clean.

Does OutSends include custom tracking domains?

Yes! Custom tracking domains are included on all paid OutSends plans starting from our $19/mo Starter tier.
