Event Promotion Case: Driving 500 Registrations in 7 Days with Rented Profiles

Events are high-stakes, high-reward marketing initiatives. Whether it's a webinar, conference, product launch, or industry summit, event success often comes down to registration numbers—and the quality of those registrations. Traditional promotion channels (email, social media ads, content marketing) have their place, but they rarely deliver the volume and targeting precision needed for aggressive registration goals.

LinkedIn outreach through rented profiles has emerged as a powerful channel for event promotion. The ability to reach thousands of precisely-targeted prospects with personalized invitations—appearing to come from relevant industry peers rather than marketing accounts—produces registration numbers that other channels struggle to match.

This case study documents how one B2B SaaS company used 15 rented LinkedIn profiles to drive 500 event registrations in just 7 days for their annual user conference. We'll cover the complete strategy: targeting, messaging, profile selection, sequencing, and the results they achieved. The principles apply whether you're promoting a webinar, conference, workshop, or any other B2B event.

If you've ever needed to fill an event quickly with qualified attendees, this case study provides a proven playbook.

The Challenge: 500 Registrations in 7 Days

The company, a mid-market SaaS provider, was hosting their annual user conference. With 6 weeks until the event, registrations were tracking well behind target. They needed 500 additional registrations from their target audience—VP and Director-level decision-makers in their key verticals—within the final week of the registration period.

Traditional channels were already maxed out. Their email list had been contacted multiple times. LinkedIn ads were running but delivering registrations at $150+ each. Content promotion was generating awareness but slow conversions. They needed a channel that could deliver high-intent registrations quickly and cost-effectively.

The constraints were significant: 7-day window, specific target personas, and a need to maintain brand reputation (no spammy outreach). The solution needed to be scalable, targeted, and produce qualified registrations—not just high volume of low-quality signups.

The Strategy: Multi-Profile Coordinated Outreach

The core strategy was straightforward: use rented LinkedIn profiles to reach the target audience with personalized event invitations at a scale impossible with a single profile. But the execution details made the difference between success and spam.

Profile Selection: They rented 15 profiles from 500accs, specifically selecting profiles with backgrounds relevant to their target audience. For a SaaS user conference, this meant profiles with technology industry backgrounds, appropriate seniority levels, and connection networks that included their target companies.

Targeting Precision: Using Sales Navigator, they built a prospect list of 10,000 qualified targets: VP and Director-level professionals at companies using competitive or complementary products, in their key industry verticals, located in regions they served.

Message Positioning: Rather than leading with the event pitch, messages positioned the sender as a peer sharing something valuable. The event was framed as an opportunity to learn from industry leaders and connect with practitioners facing similar challenges—not as a sales or marketing promotion.

Sequence Design: A 3-touch sequence spread across the 7 days: connection request with brief context, first message with event details and value proposition, and reminder message with urgency as the deadline approached.

Targeting and List Building

The quality of the target list determined the campaign's success. Poor targeting would mean low acceptance rates, low message engagement, and registrations from people who wouldn't attend or weren't qualified.

They used Sales Navigator's advanced filters to build a highly qualified prospect list:

• Title filter: VP, Director, Head of, Senior Director—the decision-making level that would benefit most from the conference and had budget/authority to attend
• Industry filter: Their key verticals where the conference content was most relevant
• Company size filter: 100-5000 employees—their sweet spot for the SaaS product
• Technology filter: Companies using specific tools in their ecosystem, indicating fit
• Geography filter: US-based or regions they could serve, given conference logistics

This filtering produced a list of approximately 10,000 prospects. They validated a sample to ensure quality, then distributed the list across the 15 profiles—approximately 670 prospects per profile, with overlap prevention to avoid multiple profiles contacting the same person.

Message Sequence and Positioning

The message sequence balanced personalization with scale. Complete customization for 10,000 prospects was impractical, but templates with strategic personalization points achieved strong engagement.

Connection Request (Day 1-2):

"Hi {FirstName}, noticed we're both in the [industry] space and thought it would be valuable to connect. I've been following some interesting developments in [topic] and always enjoy connecting with others working on similar challenges."

The connection request avoided any event mention, focusing on peer-to-peer networking. This improved acceptance rates compared to leading with the ask.

First Message (Day 2-4, after connection accepted):

"Thanks for connecting, {FirstName}! Wanted to share something that might be relevant given your role at {Company}. [Event Name] is coming up on [Date]—it's the industry's leading gathering of [description]. Speakers include [notable speakers]. Given your focus on [topic], thought you might find it valuable. Here's the link if interested: [link]"

The first message introduced the event with clear value proposition and social proof (speakers). It was conversational rather than promotional and included a clear but soft CTA.

Reminder Message (Day 5-7, for non-responders):

"Quick follow-up on [Event Name]—registration closes [date]. I know schedules are busy, but wanted to make sure you saw this in case it got buried. Several people from [similar companies] will be there. Let me know if you have any questions!"

The reminder added urgency and social proof (peer companies attending) while remaining helpful rather than pushy.

Execution and Daily Management

Executing the campaign across 15 profiles required careful coordination to maintain quality and avoid issues.

Day 1: Launched connection requests from all 15 profiles. Each profile sent 40-50 connection requests, staying well under LinkedIn's limits. Messages were staggered throughout business hours to appear natural.

Days 2-3: Continued connection requests while starting first messages to those who had accepted. Acceptance rate monitoring began—profiles with unusually low rates were flagged for review.

Days 4-5: Connection request volume reduced as the prospect pool was addressed. Focus shifted to first messages for newly accepted connections and reminder messages for non-responders.

Days 6-7: Final push with reminder messages emphasizing deadline urgency. Registration tracking intensified with hourly monitoring.

Daily standups reviewed performance by profile, identified any issues, and adjusted approach as needed. One profile showed significantly lower acceptance rates and was paused—investigation revealed a fingerprint configuration issue that was corrected.

Results and Performance Analysis

The campaign exceeded its goal, delivering 512 registrations in the 7-day period. Here's the detailed breakdown:

The 40% connection acceptance rate exceeded benchmarks, attributed to careful profile-audience matching and non-promotional connection requests. The unusually high response-to-registration ratio (172%) indicates that many recipients registered directly from the first message without responding—the clear CTA with registration link enabled this frictionless conversion.

Cost Analysis and ROI

The total campaign investment included profile rental (15 profiles × 7 days), automation tool costs, and labor for setup and management. The fully-loaded cost per registration came to approximately $12.

Compare this to their LinkedIn Ads channel, which was delivering registrations at $150+ each, or their email channel, which had exhausted its list with diminishing returns. The LinkedIn outreach channel delivered 12x better cost efficiency than paid social and reached prospects who couldn't be accessed through other channels.

Beyond the direct registration cost, the campaign generated ongoing value. The 1,138 new connections became part of the company's expanded LinkedIn network, available for future outreach. Post-event follow-up sequences converted several attendees to sales conversations, with pipeline value significantly exceeding the campaign investment.

Key Success Factors

Several factors contributed to the campaign's strong performance:

Profile Quality: Premium rented profiles with relevant backgrounds improved both acceptance rates and perceived legitimacy of the outreach.

Targeting Precision: Tight targeting ensured prospects were genuinely qualified for the event, improving conversion rates and attendee quality.

Message Positioning: Peer-to-peer framing rather than promotional messaging increased engagement and reduced negative sentiment.

Sequence Design: Multi-touch sequences with appropriate spacing captured prospects at different engagement moments.

Operational Excellence: Daily monitoring and quick response to issues kept the campaign on track throughout.

Timing: Concentrated 7-day execution created urgency without allowing prospects to forget about the event.

Lessons for Future Event Campaigns

This case study validated several principles applicable to future event promotion campaigns:

Start Earlier Next Time: While the 7-day sprint worked, starting 2-3 weeks earlier would have allowed more complete prospect coverage and less intensive daily management.

A/B Test Messages: With 15 profiles, there was opportunity to test message variants systematically. Future campaigns should build in controlled testing to optimize conversion rates.

Segment by Persona: Different messages for different job functions (VP Marketing vs. VP Sales, for example) could improve relevance and conversion.

Coordinate with Other Channels: Prospects reached by LinkedIn outreach who also received email follow-up showed higher conversion. Multi-channel coordination amplifies impact.

Plan for Follow-Up: The new connections are an asset. Build post-event nurture sequences to convert attendees and non-attendees alike over time.

Conclusion

Event promotion through rented LinkedIn profiles offers a powerful alternative to traditional channels. The ability to reach precisely-targeted prospects with personalized invitations—at 10-15x better cost efficiency than paid alternatives—makes it an essential tool for any B2B marketer responsible for filling events.

The keys to success are the same as any LinkedIn outreach: quality profiles, precise targeting, thoughtful messaging, and disciplined execution. Apply these principles to your event promotion, and you'll find registrations that once seemed impossible become achievable.
