Full Control Over Your Email Campaigns

We’ve heard you loud and clear: the single biggest concern from our early users has been emails sending without explicit approval.

Today, I’m excited to announce our new Email Approval & Control System, designed to give you full control without slowing you down:

Option 1: Auto-Send

Emails go out automatically. Hands-free, seamless, perfect when you want speed.

Option 2: Review & Approve

Nexuscale drafts each email and notifies you. You can review, edit, or approve before anything is sent. Full oversight, zero surprises.

Why this matters:

• Early users report feeling much more confident running campaigns.
• It directly addresses one of the main sticking points for new buyers.
• Makes the product dramatically easier to adopt for teams of any size.

At Nexuscale, we’re building automation that works for you, not the other way around. This update is a big step toward letting you command results without compromise.

Hey Sumo-lings,

A little tweak we’ve been meaning to add: soon you’ll have more control over your campaigns.

• Pause Campaign Button – stop a sequence anytime.
• Auto-send vs. Approval – choose if emails go out automatically or if you want to approve the first send.

We’d been planning these updates as part of making campaigns more intuitive, but your feedback helped us prioritize them sooner. Small changes, big impact, especially while we keep expanding integrations, expanding our lead database and other improvements.

— Kevin, CEO @ Nexuscale

Hi everyone,

We’re excited to share some fresh updates that many of you have been waiting for:

✅ Country selection — you can now pull leads from any country in the world for full global reach.

✅ One-time password login — a faster, more secure way to sign up and log in.

And that’s just the start. Here’s what’s coming next (our current top priorities based on your feedback):

• Company upload & enrichment — upload a list of companies and we’ll find the right leads for you
• Company name, URL, and department filters — zero in on exactly who you want
• SMTP/IMAP upload — bulk mailbox upload made simple
• Faster contact upload — smoother and more efficient workflows
• Smarter follow-up emails — crafted to boost engagement and response rates
• Improved loaders & UI refinements — better experience when generating emails, cloning agents, etc.
• Product editing inside the platform — update your product details without starting over

Your feedback has been shaping every step of our roadmap. If there’s a feature you’d like us to prioritize, I’d love to hear from you directly at kevin@nexuscale.ai.

Thank you for your support and for being early adopters!

To Your Success,

Kevin Kariuki & The Nexuscale Team 🎉

What are past projects, failures, or successes you’ve had in your career?

For the past decade, I've been deep in the trenches of B2B sales, most recently leading a team of 12 as a Business Development Manager. One of our biggest operational successes was consistently hitting targets, but it came at a hidden cost that ultimately shaped my path to Nexuscale. The challenge – and I see this as a widespread issue we were grappling with – was the sheer number of tools required just to function. My team needed 6-7 different platforms for outreach alone, and our VP of Sales was juggling another set. It was a constant battle of managing subscriptions, data silos, and training. A significant 'failure' I observed across the industry, and one we experienced, was the declining productivity of even top performers. I saw my best reps spending up to 40% of their valuable time just managing these tools instead of actually selling. That's a massive drain on potential. When AI began to really emerge, I looked at this chaotic tool landscape and asked, 'Is this sustainable as AI adds even more specialized functions?' The thought of adding more point solutions felt like compounding the problem. That was the turning point. I realized that if the trend was 'more tools,' the real innovation had to be in the opposite direction. The future couldn't be 20 different tools for 20 niche functions; that's not scalable, sustainable, or good for anyone's productivity. This conviction led directly to founding Nexuscale – to build a more integrated, autonomous approach where AI doesn't just add another tool to the pile, but streamlines the entire sales process.

What’s the origin of the idea for your product?

I spent 10 years in sales, most recently as a Business Development Manager leading a team of 12 people. One of my biggest challenges was the sheer number of tools we needed - I had to buy 6-7 different tools for my team to do outreach, while our VP of Sales needed another 6-7 tools. When AI started emerging, I asked myself: Is this sustainable? How many more tools will teams need to buy just to keep up with AI capabilities? My top performers were spending 40% of their time on tool management instead of selling. That's when I realized - if everyone's adding more tools, we need to go in the opposite direction. The future of sales can't be 20 different tools for 20 different functions. It's not sustainable, not scalable, and frankly, it's killing productivity.
