Use cold email to reach many prospects cheaply and find who is interested. Use cold calls for high-value accounts, short sales cycles and following up on engaged prospects. A common mix is email first, then a call to anyone who opens a conversation.
The real question is not which channel is better, but which one fits your deal size, your list and your team's time.
Revbound sorts every reply, answers interested leads with your free times and books the meeting.

When cold calling wins
- High deal values where one meeting justifies the effort.
- Local or SMB markets where decision makers answer the phone.
- Complex offers that need a live conversation to explain.
- Following up on a prospect who already replied by email.
When cold email wins
- Large, well-targeted lists.
- Busy buyers who will read but not pick up.
- Agencies running many client campaigns at once.
- Testing messaging quickly before investing in calls.
How to combine them
A simple sequence: email on day 1, follow up on day 3, a call on day 4 to anyone who opened a conversation, then email follow ups. The email does the prospecting; the call converts warm interest. See how to build a cold email sequence.
Compliance
Rules differ by country. In the US, cold email must follow CAN-SPAM (accurate headers, a physical address and a working opt-out), and calls to mobiles fall under TCPA rules. In the UK and EU, GDPR and PECR apply. Check the rules for every country you prospect in.
