How to Train an SDR to Run Cold Email Campaigns

Training an SDR (Sales Development Representative) on cold email is more than teaching them to use a tool. Here is the complete training curriculum.

Training an SDR (Sales Development Representative) on cold email is more than teaching them to use a tool. Here is the complete training curriculum. Week 1: Foundations Teach the fundamentals: what cold email is, how deliverability works, why infrastructure matters. Have them read the key articles on your blog. Have them set up a test domain and configure SPF, DKIM, and DMARC using the free checkers at Warm Inboxes. Week 2: Tools and process Walk them through your tech stack: sending tool, CRM, data providers, enrichment tools. Have them build a small test list (50 contacts), verify it, and load it into the sending tool. Have them write a test sequence using your playbook templates. Week 3: Supervised sending Launch a small test campaign (50 to 100 emails) under supervision. Review their copy before sending. Monitor deliverability and engagement together. Debrief on results and discuss what worked and what to improve. Week 4: Independent operation The SDR runs their first full campaign independently, following the playbook. Conduct daily check-ins for the first week and weekly check-ins thereafter. Review metrics together and coach on optimization.

Ongoing training

Monthly copy workshops where the team reviews and improves email templates. Quarterly playbook updates based on new learnings. Regular training on new tools and features.

The training investment

It takes four to six weeks to fully ramp an SDR on cold email. This investment pays dividends for months — a well-trained SDR produces consistent pipeline without daily supervision.
