Marketing Investments With the Best ROI in 2025
Here are five marketing investments delivering the best ROI in 2025, and how they connect to one of the most underutilized growth channels: human-led outreach through Versatile Telephone Marketing (VTM).

Every year brings new trends in marketing, but in 2025 the challenge isn’t novelty — it’s impact. Businesses of all sizes are asking the same question:
Where should we invest our limited marketing budget to get the best possible return?
The answer lies in a balance of proven strategies and human connection. While digital tools provide reach and efficiency, the businesses seeing the strongest ROI are those that combine technology with genuine relationship-building.
1. Customer Retention Initiatives
It’s no secret that retaining existing customers costs significantly less than acquiring new ones. In fact, Bain & Company’s research shows that a 5% increase in customer retention can boost profits by 25% to 95%.
Why? Because loyal customers buy more often, spend more per purchase, and refer others. Yet many companies still funnel most of their budget into acquisition, leaving retention underfunded.
What Works in 2025
-
Personalized loyalty programs: Small rewards for repeat purchases.
-
Proactive check-ins: A call to ask how things are going before renewal dates.
-
Exclusive access: Early product releases, beta testing opportunities, or VIP events.
Example
Imagine a software provider with a database of 2,000 customers, 400 of whom haven’t logged in for 6 months. Instead of ignoring them, they launch a reactivation campaign with special offers and personal outreach. By winning back just 10% of those customers, they generate new recurring revenue — at a fraction of acquisition costs.
How VTM helps: Structured telephone calls (like those in a VTM 20 package) are one of the simplest, most effective ways to re-engage dormant customers. A quick conversation can re-establish trust and turn a “lost” client into a loyal one again.
2. Search Engine Visibility & Educational Content
In 2025, search engines remain one of the most powerful sources of leads. Why? Because people use Google to find answers and solutions when they’re already motivated to act.
According to HubSpot, 61% of marketers say improving SEO and growing organic presence is their top inbound marketing priority. Businesses that publish educational, search-optimized content earn traffic for years — without the ongoing cost of ads.
What Works in 2025
-
Evergreen blog posts: “How-to” guides, “Top 10” lists, and industry FAQs.
-
Case studies: Real success stories that double as trust signals.
-
Video snippets: Short, searchable clips embedded into posts.
Example
A training consultancy writes a blog called “Top 7 Skills Employers Want in 2025”. Optimized with keywords, it starts ranking on Google. Within months, it brings in hundreds of visits a month, leading to steady inquiries from HR managers.
How VTM helps: Content attracts attention — but human-led outreach converts it. For example, a contact who downloads a guide from your website can be added to a VTM call list. A personal follow-up turns passive interest into a conversation, which is far more likely to generate sales.
3. Relationship-Driven Email Campaigns
Email remains one of the highest-ROI marketing channels, with some studies reporting a return of £30–£35 for every £1 spent. The key in 2025 isn’t volume — it’s relevance.
Customers are fatigued by generic blasts, but segmented, personalized emails still perform extremely well. Automated journeys, when done with care, maintain touchpoints without feeling robotic.
What Works in 2025
-
Reactivation emails: “We miss you” notes with a small incentive.
-
Milestone emails: Celebrating anniversaries or renewals.
-
Educational sequences: Series that teach something useful over a few days.
Example
An e-commerce business identifies customers who haven’t purchased in 9 months. They launch a reactivation sequence: first a reminder, then a discount, then a final “last chance” message. The campaign recovers 12% of lapsed buyers, generating thousands in additional sales.
How VTM helps: Email opens the door, but it doesn’t always start a real dialogue. VTM can follow up with those who clicked but didn’t purchase, providing the human touch that pushes them from “considering” to “committing.”
4. Reputation & Customer Feedback Programs
In 2025, reputation is everything. A BrightLocal survey found that 87% of consumers read online reviews for local businesses, and B2B buyers are no different. They look for testimonials, feedback, and social proof before deciding.
Investing in reputation-building pays off — not just through improved trust, but also through valuable feedback loops. Businesses that listen and act on feedback are more likely to retain customers and improve their offerings.
What Works in 2025
-
Surveys after service delivery: Simple “How did we do?” questions.
-
Review requests: Encouraging happy customers to post on Google or industry platforms.
-
Case study interviews: Turning satisfied clients into success stories.
Example
A logistics company builds a campaign around gathering reviews from clients. With 20 new testimonials on Google and LinkedIn, they see a sharp increase in inbound leads, because prospects trust peer recommendations more than ads.
How VTM helps: VTM can run structured feedback calls, turning conversations into actionable insights. Clients feel heard, which strengthens loyalty, while businesses gain quotes and testimonials that build credibility.
5. Human-Led Outreach (The Competitive Edge)
Finally, the most underrated — yet most powerful — ROI channel in 2025: human-led outreach.
Digital channels are crowded. Automated emails, AI-driven ads, and chatbots all compete for attention. But nothing cuts through like a professional, well-timed phone call.
This is where Versatile Telephone Marketing (VTM) comes in. With over 13 years of experience, VTM helps businesses build stronger customer relationships through structured telephone campaigns. Their services are designed for flexibility:
-
VTM 20: 20 sessions for small, focused campaigns — ideal for reactivating dormant customers.
-
VTM 50: 50 sessions for SMEs looking to nurture a mix of accounts.
-
VTM 100: 100 sessions for enterprises aiming to scale outreach and open new opportunities.
Why This Works in 2025
-
Direct connection: A human voice builds trust faster than any digital ad.
-
Real-time feedback: Conversations reveal insights no survey can.
-
Scalable structure: Whether you need 20 calls or 100, VTM tailors the outreach to your budget and goals.
Example
An SME has a database of 1,000 past customers, but sales have gone quiet. Instead of starting from scratch, they invest in a VTM 50 campaign. Within weeks, VTM reconnects with dozens of accounts, revives interest, and uncovers new opportunities. The ROI far outweighs the cost.
Putting It All Together
The Top 5 ROI marketing investments in 2025 are:
-
Customer retention initiatives
-
SEO & content visibility
-
Relationship-driven email campaigns
-
Reputation & feedback programs
-
Human-led outreach (VTM)
These aren’t competing channels — they’re complementary. Retention keeps your base strong. SEO and content attract fresh attention. Email nurtures. Feedback builds credibility. And human outreach brings it all together, turning opportunities into revenue.
