From LinkedIn
“Jayson is highly skilled in creating your email marketing campaigns. There is a lot more of small important details that will make or break it for a business, and Jayson knows exactly how to set up to generate leads and have an effective campaign.”

“Jayson is easily the best person I've found at Upwork or Fiverr or any of those sites. I had badly messed up my own email sequence and got a bunch of accounts marked as spam. Jayson was smart, helpful, did the work needed so quickly but also guided me through the process gently and helpfully. I could not recommend him enough.”

“Jayson is amazing! We botched our cold email campaign and, after much research into what went wrong, we turned to Jayson for help. He quickly responded with recommendations and then proceeded to set up alternative domains that we had sitting dormant, upload our information and settings into a new email platform and set our new email domains into a warm-up period. He was fast, efficient and knowledgeable. Jayson communicated his process to us every step of the way. We couldn't be more relieved!”

From Upwork
“Jayson is amazing at what he does. He provides excellent insight on the state of email campaign setup and deliverability. His suggestions are always timely and accurate and the work he completes for us has always been top notch. And, when there has ever been a problem, seldom as it actually is, he is on top of it before we ever caught it and had already been working on the solution before we ever reached out to him. I have used him countless times, and will continue to use him again in the future. If you're considering using him, don't think anymore, just do it! You'll thank me later!”

“Jayson was extremely helpful throughout the entire setup process and did an excellent job with the Apollo and cold email infrastructure setup for us. He was knowledgeable, responsive, and very patient in clarifying things whenever needed. He also shared useful suggestions and practical recommendations to help improve the overall setup and approach, which we really appreciated. Everything was handled well, and the campaign foundation was set up properly and professionally. Overall, it was a very positive experience working with him, and we would definitely be happy to work with him again.”

“Worked w Jayson for a long time, he is a real seasoned cold email expert 🔥 knows all the ins and outs of backend setup and the campaign operations. We did Instantly.ai campaigns and he handled all the email account registration and setup and managing the campaign automations. Solid hire for managing your cold email campaigns with minimal direction.”
