Nexuscale AI Reviews

What I like:

The AI is genuinely impressive. As someone who works with LLMs daily, the prompting and personalization feel well-built. (Would love to know which LLM is used) ;)

Email personalization has three data sources (Company News, Website Analysis, LinkedIn Activity). This is a great start.

The team is under 10 people, and what they’ve already built is a solid foundation. I also like that they’re working on features such as email warm-up and health checks.

Questions and Suggestions:

Can personalization sources be combined? Right now, I have to pick one. Would it be possible to merge them for richer personalization (e.g., LinkedIn + Website + News together)?

If I pick Company News, how does it behave when the company isn’t active? Does it pull old news that might feel irrelevant?

If I pick LinkedIn Activity, does it only pull from the profile, or does it also include company-level information?

If I pick Website Analysis, can that personalization also tie to the person I’m sending the email to?

If these could work together, it would make the outreach much stronger.

What needs improvement:

Performance: The app is slow, with noticeable lag in searches and AI matches.

Bugs: For example, notifications tied to deleted agents still appear. These issues are only found through real use, but they need fixing.

Notifications: Every action triggers an email, with no option to turn them off. I received ~50 in a single day.

Campaign flow: The campaigns → agents → emails structure is confusing. Campaign goals auto-generate emails before setup is complete, and there’s no clear way to cancel or delete them. Ideally, one draft email should be generated first, then expanded only after approval.

Target lists: Importing and managing targets isn’t intuitive. Needs clearer UX.

Overall:
If you need a polished, ready-to-go solution today, this isn’t it yet. But if you’re buying AppSumo deals expecting early-stage products with growth potential, NexusScale.ai fits the bill.

My only real concern is that updates keep coming and AppSumo customers don’t get left behind. Some apps stop prioritizing lifetime deal buyers after launch, and if that happens here, it’s a no-go. But if the team continues to support and improve for all users, this could move from a 3-taco product today to 4–5 tacos in the future.

These guys LISTEN to your input. They're STILL working on the internals of things, but I feel from my conversation with the creator, that the tool is not only here to stay, but that Sumo-lings can feel confident in the longevity of the platform. This has ben a HUGE concern for many of us over the last couple years. The lead output, from your initial search input, is nothing shy of PERFECTION.. The AI email generation, if you structure your setup, and fill in everything about your business, is near perfection on it's own. The way that it create a light tone, and gentle touch is fantastic. That's my first impression. They're working on building out more training videos, and cleaning up the UI. I'm happy with it so far. Just pushed out my first 200 emails, that are throttled BTW, which is perfect. Super happy at this point, and glad to be part of this startup at it's infancy.

Nexuscale has evolved into a dependable and well-rounded platform for outbound campaigns. The interface is clean, intuitive, and makes it easy to start finding leads and launching campaigns without unnecessary setup time. The UI and marketing design both stand out, professional, modern, and easy to navigate. One standout feature is the ability to review and approve every email before it is sent, which gives full control and peace of mind, especially for brand sensitive outreach.
Campaign scheduling is also accurate and reliable. Emails are delivered according to the exact time and timezone set for each target, and the team is already working on a visual update to make timezone display even clearer. Support continues to impress. Kevin, the CEO, and the chat support team are incredibly responsive, approachable, and genuinely invested in user success.

Overall, Nexuscale feels stable, smart, and thoughtfully built. A strong choice for anyone serious about AI powered outbound.

UI is great, setup pretty straight forward. Couple of things for which I decided to refund highest tier:
1. Leads are not high quality, bunch of them when you click on Linkedin, takes you to 404 Linkedin page
2. I read couple of emails that it wrote, as a marketer I have to say they are pretty questionable for cold reach, not quite sure how much is personalized properly
3. When you tring to search leads in "less" developed country, you really see the lack of it
4. You have to believe that it has high deliverability late, there is no way to be sure
5. Sheduling overlap - you can have bunch of agents being sheduled to send on same date which in total is over the daily limit you already set, so I got no idea are those mails sent the same day or tomorrow - maybe I missed it somewhere as a option and there is no notice like in hubspot sales proffesional.
6. 50.000 emails alone should be enough to get this deal if you have your own target list, but because of
need to believe that it works, and the fact that on over 3,4 weeks of testing the software with 2000 emails limit monthly, we didnt get a single reply, I have doubts that is effective, I dont know are they legit or I am just losing my patience with new tools :)

Overall impression, it has potential, but the feeling that all of us are used just for testing and product improvement :) Hope we helped and I hope I will regret for refunding your tool :) Thank you anyway

the saas just felt dated it didn't even have a html for email and the ai generation was failing to generate properly im so disappointed as i had issue with activation but founder did provide support but when i realized i couldn't add a proper campaign only text i had to give this up I dont understand high reviews on something that is not effective it makes me think so users dont really engage in the product for proper review I thought all the bugs was worked out but tier 5 is way over priced for something that is still in development of this sort i guess i have to use my encharge deal much more solid platform!
