      Email Marketing Review from Atif Gagguturu

      We are a document collection specializing in loan document gathering and invoice management software company. We hired LevelUp Leads to increase the amount of sales and demos we got.So we have been having trouble getting leads. As such we were searching for a marketing company to help us find more customers. We stumbled upon LevelUp Leads and found they came with a lot of good recommendations. It is benefiting us by giving us a better direction to get more leads. I like the weekly reviews where we can see what we are doing good. I also like being given reports of who is being responsive to our campaigns. I like how the LevelUp Leads explains what exactly the campaigns are doing and why they are doing the things they are doing and how it can get us out there. I especially like the recommendations given to our company for our other advertising projects.

      Levelup Leads provides various digital marketing services for our healthcare testing services company. The team's tasks range from paid media and reporting to email campaign optimization and landing page creation. We are pleased with Levelup Leads' services. What's been most impressive about the team is their project management skills, they execute tasks efficiently and hold weekly meetings to ensure everyone's in synchronization. Their problem-solving capabilities are commendable as well.

      Email Marketing Review from Josh Kaye

      I recently engaged Cience Lead Generation, paying $10,000 for 250 qualified leads, expecting a professional service and solid prospects. Unfortunately, what I received was far from that. The leads they presented were completely fabricatednone of the individuals or businesses had requested information about my company. In fact, we obtained sworn affidavits from many of these so-called "leads" affirming they had never heard of us or requested any information.This is a blatant scam, and we're now in the process of pursuing legal action against Cience to recover our full payment. If you are considering working with them for lead generation, I strongly urge you to reconsider. Their practices are fraudulent, and you risk losing a significant amount of money without getting anything of value in return. We were misled, and now we're facing the consequences of trusting this company. Dont make the same mistake.

      B2B Review from Greg Digneo

      Best decision we made last year was partnering with this CX team for our customer support, billing, and sales assistance. We were drowning in client emails and chasing invoices late at night instead of focusing on SEO strategy. Results have been incredible: client response times dropped from hours to under an hour, payment collection improved 60%, landing page conversions up 28%, and client retention increased 35%. They integrated seamlessly with our systems and scaled with us as we grew. Now we have more time to focus on delivering SEO results instead of being stuck in support tickets all day. If you're an agency juggling client support with campaign management, this team is a game-changer.

      I have reviewed the industry in late 2021 both from technical and non-technical viewpoints. The Jumio solution, a platform hosting a full suite of KYC & Identity Verification, AML and more, offers well documented API on github and user support channels. The KYC is consistent and accurate and importantly the solution integrates well with your internal company systems regardless of tech stack.
