Best Practices

Personalize cold outreach with specific research — reference their website, recent content, or industry

Lead with value, not credentials — show what you found, not your portfolio

Include measurable results in project updates (traffic, conversions, revenue)

Follow up on proposals within 3-5 business days

Re-engage past clients with relevant new services, not generic check-ins

Common Mistakes

Sending generic cold outreach without researching the prospect

Leading with your agency's credentials instead of the prospect's needs

Not including results or metrics in project update emails

Following up on proposals too aggressively (daily) or too passively (never)

Treating all prospects the same instead of segmenting by industry or need

Personalization Tips

Your outreach is your portfolio

For agencies, cold outreach serves double duty. It's both a prospecting tool and a demonstration of your capabilities. If your outreach emails are generic and uninspired, prospects will assume your client work is too. Make every email a showcase of the clear, strategic thinking you'd bring to their business.

The best agency outreach starts with research. Reference something specific you noticed about the prospect's website, marketing, or industry. Then connect it to a result you achieved for a similar client.

Project updates are retention tools

Client churn is the silent killer of agency growth. Regular project updates that show measurable progress — traffic increases, conversion improvements, revenue impact — remind clients why they're paying you. They also preempt the "what are we actually getting?" question that leads to cancellations.

Include KPIs in every update. Numbers build trust and justify retainers.

Past clients are your warmest leads

Re-engaging past clients is easier than winning new ones. You already have trust, context, and a track record. When you launch a new service or capability, reach out to past clients who would benefit. The conversion rate on these emails is dramatically higher than cold outreach.
