🎯 BEST USE CASES

When to Use Email vs SMS

📧 Use Email When:

Detail and design matter. Product launches, newsletters, long-form content. Email supports rich design.

Building relationships. Welcome series, educational content, storytelling. Email nurtures better than SMS.

You have tight budgets. Email is nearly free at scale. Perfect for cost-conscious campaigns.

Content is complex. Detailed product information, guides, comprehensive updates need email format.

Branding is crucial. Custom templates, logos, visual identity are email's strength.

You need deep personalization. Segment audiences by behavior, purchase history, preferences easily in email.

📱 Use SMS When:

Time is critical. Appointment reminders, order confirmations, payment alerts. SMS reaches customers instantly.

You want high engagement. Flash sales, limited-time offers, urgent updates. 45% CTR beats email's 3-5%.

Simplicity matters. A quick text beats a full email that might not get read for hours.

You target mobile-first audiences. SMBs, millennials, Gen Z prefer text notifications.

Response rates matter most. Customer confirmations, two-way conversations, immediate actions.

Budget allows. At £0.04-£0.10 per message, SMS cost is justified by 10x better ROI.

Real UK Business Examples

  • Salon: Email for monthly newsletters and promotions (build loyalty). SMS for appointment reminders (98% see it, no-shows drop).
  • E-commerce: Email for product recommendations and educational content (nurture). SMS for cart recovery and flash sales (instant, high-converting).
  • Restaurant: Email for seasonal menus, loyalty program updates, event invites. SMS for table availability alerts and wait times.
  • Fitness: Email for workout tips, nutrition guides, success stories. SMS for class reminders and booking confirmations.
  • Delivery: Email for feedback requests and repeat offers (relationship building). SMS for live order tracking and ETAs (time-critical).
💰 COST ANALYSIS

Email vs SMS: Cost Comparison

Cost Per Campaign (1,000 Recipients)

  • Email: 1,000 messages = £0 cost (most platforms). Cost per conversion at 2% = £0 per sale (only platform fees apply).
  • SMS: 1,000 messages × £0.07 per SMS = £70 total cost. Cost per conversion at 20% = £3.50 per sale.
  • Verdict: Email costs less upfront. SMS costs more per message but generates 5-10x higher conversions, lowering cost per conversion.

ROI Breakdown: Which is Better Value?

  • Email ROI Example: 1,000 emails at £0 cost. 30% open, 3% CTR = 9 clicks. 10% conversion = 0.9 sales. £50 AOV = £45 revenue. Profit = £45. ROI = Infinite (no cost).
  • SMS ROI Example: 1,000 SMS at £70 cost. 45% CTR = 450 clicks. 20% conversion = 90 sales. £50 AOV = £4,500 revenue. Profit = £4,430. ROI = 6,328%.
  • Realistic Email ROI: With platform costs (£50/month for 10,000 emails). £50 ÷ 10 campaigns = £5 per campaign. ROI = (£45 - £5) ÷ £5 = 800%.
  • Winner: SMS generates 8x higher ROI than email on same budget. Email is cheaper to run. Use SMS for revenue, email for relationship building.
🏆 THE VERDICT

Email vs SMS: Which Should You Choose?

The Best Strategy: Use Both Channels Together

Leading UK businesses don't choose between Email and SMS - they use both strategically:

  • Email for nurture and relationships. Newsletters, educational content, product launches, loyalty programs. Build trust and long-term customer value.
  • SMS for urgency and conversions. Appointment reminders, cart recovery, flash sales, time-sensitive alerts. 98% open rate and 45% CTR drive immediate action.
  • Combined reach and frequency: Email reaches those who opt-in. SMS reaches 100% of customers (any phone). Together they ensure complete coverage.
  • Complementary timing: Email works as background nurture between SMS campaigns. SMS acts as interrupt-driven immediate response.
  • Dramatically better results: Combining Email + SMS achieves 20-30% higher conversion than either channel alone.
  • Budget efficiency: Email is cheap for nurture. SMS costs more but drives conversion. Together they maximize efficiency.

❓ COMMON QUESTIONS

Frequently Asked Questions

Everything you need to know about switching or combining channels

Can I manage both Email and SMS in one place?

Yes! Team-Connect offers a unified dashboard where you can design emails, draft SMS messages, manage contacts, and view analytics for both channels side-by-side.

Is SMS marketing legal in the UK?

Absolutely, provided you follow GDPR and PECR regulations. This means you must have explicit consent (opt-in) from customers and offer a clear opt-out method. Our platform handles this automatically.

Do I need a designer for Email Marketing?

Not with Team-Connect. We provide professional, mobile-responsive drag-and-drop templates. You can create beautiful emails in minutes without any coding or design skills.

Why does SMS cost more than Email?

SMS relies on mobile network infrastructure which charges a termination fee per message. Email uses internet data which is essentially free. However, the higher ROI of SMS often offsets the cost.

Can I send SMS to landline numbers?

Standard SMS cannot be sent to landlines. Our system automatically validates numbers to ensure you only pay for messages sent to valid mobile devices, saving you money on wasted sends.

How do I collect phone numbers for SMS?

The best way is to add a phone number field to your email sign-up forms, offering a small incentive (like "10% off") for customers who opt-in to text alerts.

What is a good open rate for Email?

In the UK, a 20-30% open rate is considered healthy across most industries. If you are seeing rates below 15%, we recommend cleaning your list or improving your subject lines.

Can I automate messages?

Yes. You can set up flows like "Welcome Series" (Email) or "Abandoned Cart" (SMS) that trigger automatically based on customer actions, so you make sales while you sleep.
