Key Takeaways

  • 10% email conversion rate from the initial campaign, which got 500+ positive responses.
  • 30% productivity boost through automated sequences 
  • Improved email deliverability and real-time responses with Smartlead’s master inbox. 

A Bit of a Background

Nandini Jain is the Head of Growth at SalesUP, a B2B sales agency dedicated to simplifying sales for B2B startups. SalesUP provides tech-enabled sales solutions, including an extensive sales database and sales-qualified meeting setups, to help businesses scale. They assist startups in reaching a global audience through multiple outreach channels like Email, LinkedIn, WhatsApp, and more.

SalesUP recently launched a new Data Enrichment Tool, which allows B2B sales agencies to source accurate emails and phone numbers through a waterfall of 30+ providers. However, like many growing businesses, SalesUP encountered a few challenges executing successful cold email campaigns.

Challenges Faced by SalesUP 

Before using Smartlead, SalesUP faced three main obstacles:

  1. Email Deliverability Issues: Experimenting with content while maintaining email deliverability was challenging.
  2. Multi-Audience Reach: Reaching a diverse audience without hurting deliverability metrics across multiple outreach channels was a concern.
  3. Manual Workload: Managing responses and inboxes manually consumes time and resources.

They needed a solution to streamline their cold email campaigns and improve deliverability while cutting down on manual tasks.

The Solution: Smartlead's Cold Email Marketing Platform

After learning about Smartlead from other email marketing experts on LinkedIn, Nandini and her team decided to integrate Smartlead into their operations. They’ve been using Smartlead for over a year now, and it’s become a crucial part of their lead generation strategy.

Key Features of Smartlead That Solved SalesUP's Challenges:

  • Email Deliverability & Warmups: Smartlead’s email warmup system and deliverability management tools allowed them to reach multiple audiences without risking deliverability issues.
  • API Integration & Webhooks: Seamless integration with their internal systems helped SalesUP manage their cold email campaigns effectively.
  • Subsequences: These automated responses saved the team time by managing inboxes, auto-tagging leads, and responding to out-of-office replies.
  • Slack Community Support: Beyond just using the tool, SalesUP benefited from Smartlead’s Slack community, which provided valuable insights on cold email marketing strategies.

The Campaign: Driving Success at a Major B2B Event

SalesUP wanted to leverage an upcoming B2B event in India to gather leads for one of their clients. Instead of the typical outreach before the event, they decided to try something different using Smartlead’s cold email platform.

  1. Data Scraping & Email Sequence Setup:
    They scraped the application and set up a sequence targeting attendees at the event. Their email pitch was simple:
    “We know you're attending the event. We have the attendee list, and we're offering it along with free credits to check out our product. Reply with ‘yes’ if you’re interested, and we’ll send you the details.”
  2. Automated Follow-Up Sequences:
    If any recipient replied with “yes,” Smartlead’s automated subsequences triggered a response with the attendee list and a link to sign up for their client's platform. This ensured that every interaction was handled without manual intervention.

Major Results Achieved Through Smartlead

The campaign was a resounding success. Key metrics include:

  • 500+ responses to the initial email.
  • 10% of respondents signed up for their client’s product platform, generating high-quality leads directly from the event attendees.
  • Significant time savings: Smartlead’s automation features saved SalesUP hundreds of hours that would have otherwise been spent managing replies and handling follow-ups.

Key Benefits Of Using Smartlead’s Cold Email Solutions

  1. Improved Deliverability:
    Smartlead’s warmup and deliverability management features ensured that their emails landed in the inbox, resulting in a higher open rate than their previous campaigns.
  2. Streamlined Campaign Management:
    The subsequences and automation tools handled responses, managed inboxes, and sent follow-up emails, reducing the need for manual labor by over 60%.
  3. Increased Engagement:
    By tailoring the email content to the event, SalesUP achieved an impressive 10% conversion rate, with leads signing up to check out the product.
  4. Time Efficiency:
    The automated responses and management tools allowed SalesUP to focus on high-priority tasks rather than spend time on inbox management, resulting in a 30% productivity increase.

Conclusion

By leveraging Smartlead’s cold email marketing platform, Nandini and her team at SalesUP was able to automate critical elements of its campaign, increase lead conversion rates, and significantly reduce manual tasks. 

Smartlead’s features, such as email warmups, subsequences, and API integration, played a crucial role in SalesUP's successful outreach during a high-stakes B2B event, helping them drive real business results.

Quote from Nandini, Head of Growth at SalesUP:
"Smartlead has become a cornerstone of our email marketing strategy. The automation features not only saved us time but also ensured that we didn’t miss out on any potential leads. With more than 500 responses and 10% of them signing up, the results speak for themselves. We couldn’t have achieved this level of success without Smartlead’s help."
