The answer: both.

Frequently Asked Questions
1. Is email or social media better for conversions?
Email tends to outperform social media when it comes to direct conversions, thanks to first-party data and personalization.
2. Can I use the same content across both channels?
Yes, but adapt it. Repurpose social content for email newsletters and share email success stories via social media.
3. What’s the ideal email frequency vs. social posting schedule?
Email: 1–4 times per week depending on audience. Social: Daily posting + Stories/Reels 3–5x weekly for momentum.
4. How can I grow my email list using social media?
Run lead magnets, quizzes, and giveaways that require email sign-up. Promote with paid ads and Stories.
5. Should I invest in social ads or email automation first?
If your list is small, start with paid social to drive traffic. Then invest in email to nurture and convert that traffic.
6. Do I need different teams for email vs. social?
Not necessarily. Many brands centralize content planning with platform-specific adaptations by channel experts.
Final Thoughts
Email and social media marketing are powerful on their own—but unstoppable together. The real question isn’t which to choose, but how to use them together strategically.
Email gives you ownership, data, and conversions. Social gives you reach, relatability, and rapid engagement. Brands that master both—and align them with smart tools, creative repurposing, and integrated targeting—create unstoppable growth machines.
