The Problem With Email-Only Outreach

Declining Email Response Rates (2024 Data)

Cold email response rates have plummeted to 1.7% (Salesloft, 2024), making single-channel outreach ineffective. Key findings:

• B2B tech: 1.2% avg response rate
• Professional services: 2.1% (highest among industries)

Industry Benchmarks (B2B vs. B2C)

(Table: Response Rates by Industry)

Why Inbox Overload Kills Conversions

• Average professional receives 121 emails/day
• 68% of cold emails get deleted in <3 seconds

How Buyers Consume Content Today

The 7-Touch Rule for Modern Sales

Buyers need 7+ touchpoints before engaging (Gartner). Example sequence:

1. LinkedIn connection
2. Email #1
3. Comment on post
4. Email #2
5. Cold call
6. SMS
7. Breakup email

Channel Preference by Age/Demographic

• Gen Z/Millennials: 83% prefer SMS/LinkedIn
• Gen X/Boomers: 61% still respond to calls

The Power of Multichannel Sequences

Why Mixing Channels Works

The “Rule of 3” (Email + Call + Social)

Combining 3 channels increases response rates by:

• 142% for lead gen (InsideSales)
• 89% for meeting bookings

How Repetition Builds Familiarity

• Brand recognition jumps from 12% to 64% after 6 touches
• Response likelihood increases 5X by message #5

Optimal Channel Combinations

LinkedIn + Email + SMS (Highest Response Combo)

Sequence Example:

1. Day 0: LinkedIn connection + note
2. Day 1: Email with personalized intro
3. Day 3: SMS with value proposition

(Result: 38% reply rate vs. 11% email-only)

When to Use Video vs. Voice Notes

• Video: Complex pitches (72% higher recall)
• Voice notes: Quick updates (3X faster responses)

Step-by-Step Multichannel Follow-Up Framework

Day 1-3: The Initial Touchpoints

Email #1 (Personalized Hook)

Template:

“Hi [First Name],

I noticed [specific trigger] and thought you might find [resource] helpful.

Would Tuesday at 3pm work to discuss how we helped [Similar Company] achieve [result]?”

LinkedIn Connection Request (With Note)

Best Practice:

• Reference shared connections
• Mention recent post engagement

Day 4-7: The Reinforcement Phase

Cold Call Script (Mentioning Email)

“Hi [Name], this is [You] from [Company]. I just sent you an email about [value prop] – did you get a chance to review?”

SMS/WhatsApp Follow-Up Template

“Hi [First Name], circling back on my email. Would love your thoughts on [specific insight]. Reply STOP to opt out.”
