About cold.email

Written by the company

We book over 1000 opportunities per month through cold email.

As a former SDR/AE/sales leader, I have seen Apollo and Zoominfo not deliver the data my sales teams needed.

This is when I started researching better solutions like Clay, AI agents, Instantly and custom web scraping tools. I started building lists from scratch, and little by little became a very skilled list builder.

I figured out how to leverage technology to...

     1. Custom build lists of leads not in traditional databases. Imagine building a list of your entire total addressable market in just 1 day.

     2. Build AI Agents that could do deep research and prospecting. Qualify and research every single lead in your TAM, in just 1 day.

     3. Send cold emails at scale, that are relevant so every email looks like it was written by a human, and converts.

I used to make cold calls; making over 100,000 in my career. I used to think cold email was dead. Until I learned how to do it correctly.

Within months, I was booking hundreds of opportunities per month. With my strong understanding of sales, I was able to quickly apply technology to my processes. My biggest regret was not learning sooner.

I built a brand on Upwork, quickly becoming the #1 cold email expert on the entire platform. I also started my own youtube channel to share what I learned. I was consulting, and hiring and training people on my processes, so we could help more clients. Before I realized it, I was an agency owner.

Wanting to be very clear in what our business did, I branded under cold.email

We are now one of the top cold email agencies in the world, generating over 1000 meetings per month.

Results from Two Week Test

We ran a two week test and these are the results:

- 18 Activated Leads (meaning DMs said they 'want to meet or talk')
- 7 booked first meetings.
- 4 Proposals
- 3 Pending Closes (as of the end test period)

Mr. Worthington accomplished three things that we could not do in our past cold outreach efforts, using both outside experts and in house expertise:

1. finding enough leads and contacts.

2. achieving the right dense sequencing & hyper personalization.

3. achieving a volume of qualified activated leads.

What Mr. Worthington represented was delivered.

His tech stack is excellent and easy to use, and his team is very responsive and supportive.

No need to embellish. The facts speak for themselves. I am glad to be working with Tanner.

During this free trial, I am glad we were able to instill confidence we can deliver good results for you, as well as earn your business. Our pay per lead program, with no setup fee, no software costs, no monthly retainer, no CC, and no account creation is meant to be as frictionless as possible, so we can show you what we are made of, investing all our own money, and taking on all the risk since we are confident we can deliver leads for you. We also appreciate being able to work with you on Upwork.com where we can show other clients, the associated spend with your contract, to provide transparency, one of our key values.

John was extremely helpful and generous in his consultation with me, he provided a ton of valuable insight. There is no other cold email agency that you can work with that has the knowledge, the advanced skill, and will put in the time for you on the market. 100% work with him if you're looking to turn cold email into your best revenue source

If you want results, look no further...

There are people doing cold email and there is John and his team.

My grandpa always used to say: "The one who buys cheap, buys twice". Don't be that guy, work with John and you won't have to look further.

The impact he had on our business is definitely significant.

We were about to hire 3 more SDRs, but after a conversation with John it was clear, we'd have a better performance working with him, while saving the salaries, which allowed us to be more flexible due to the reduced headcount.

Any business that has a strong product or at least 1 solid sales rep on their team will benefit working with cold.email without a doubt.

I'm a business owner looking to take my email marketing to the next level. I found John to be extremely knowledgeable. To a novice such as myself, he was able to break things down into concepts that I could understand. All my interactions with him were concise, to the point, and gave me the actionable steps I needed to take with my business. If you need assistance with your cold outreach emails, John is your guy.

This guy knows his cold email game

Just had a call with John from Cold.Email and it was exactly what I needed. He broke down email setup, domain management, and showed me tools like Clay.com for finding leads and Instantly.ai for warming up mailboxes.

I appreciated his honesty - he didn't sugarcoat how complex cold email can be. Instead, he shared some really useful videos and resources that made things clearer.

Despite our weird timezone situation, John made time for a call and was super patient walking me through everything. No wonder his agency is ranked #1 on Upwork.

If you're looking to run cold email campaigns or just need to know what to look for when hiring someone, John and his team are definitely worth talking to.

We were looking to generate leads for our product in retail stores, and John Tanner Worthington and the cold.email team brought us 30 HOT leads in 48 hours. We closed 70% of them. We had been working with some cold callers for a few months but the cold email performed much much better.

It was incredible how he was able to scrape local businesses, use AI to qualify them, and also build out AI Agents to personalzie the emails at scale. Customers were responding "Wow its very clear you researched our company and I usually ignore most cold emails, but your industry knowledge and personalization made me respond. Id like to take a call" I cant recommend cold.email enough, and is a better option than a cold caller.

Hey Gary, I appreciate the kind words. Most agencies just book unqualified leads trying to get their numbers up. We really focus on building extremely personalized lists through custom code,web scrapers, AI agents and purchased intent data. These reviews are what make all the hard work worth it. Thanks so much.

Highly recommended

John Tanner and his team at cold.email have genuinely transformed our approach to lead generation. From the first conversation, John's professionalism, transparency, and depth of knowledge stood out clearly. Unlike many other services, John took the time to understand our business deeply, ensuring each cold email campaign was meticulously tailored to our target audience.

The systems he leverages, including Clay and Instantly, are powerful and incredibly effective. The personalization and precise targeting capabilities are unlike anything we've experienced before, generating exceptional response rates and high-quality leads consistently.

We saw immediate, measurable results, and John continued optimizing our campaigns to surpass our expectations continuously. His team is proactive, detail-oriented, and genuinely committed to delivering outstanding outcomes.

I highly recommend John Tanner and cold.email to anyone serious about elevating their lead generation efforts through cold email. It's one of the best investments we've made.

Hey Ivan, we strive to deliver immediate results for all clients, no matter their industry or offer. While this isnt possible 100% of the time, we do have a good understand of best processes to use to drive results quickly, and I am suppy happy we were able to do this in your case.

AI Personalization, and custom list building are extremely powerful tools when done correctly. (its hard to know where to start!!! We like using clay, perplexity, 4o integrated into custom softwares, and Python to achieve these)

I've been doing my own cold emailing…

I've been doing my own cold emailing for 10+ years but finally decided to take a chance and work with an agency to handle it for me and I am SO glad I found John Tanner Worthington. He's an absolute legend and helped me find new ways to get the right contacts for the exact types of customers I wanted to reach, which meant we were able to deliver good emails to more people, which meant more replies, which led to our emails hitting more inboxes than before / less spam reports. I thought I was doing good enough, but working with John and the Cold.Email team taught me "good enough" was actually costing me a lot more money. If you want to get more customers through cold email, try them out!

Hey Justin,

A lot of clients dont understand this!!! Cheaper is not always cheaper. We have clients all the time who say "Well I can work with a contractor and do this for half the price!"


You may pay half as much, but you will only get 1/10, or 1/20th the result. So is it really half the cost? Its actually 10x as expensive, because of all the money you are leaving on the table.

Cold Email and the lead generation space is FULL of fake gurus, inexperienced professionals, or people who just want to make a quick buck, and its hard to get that taste out of some peoples mouths, but we do our best, to show that not all agencies are that way.

It takes a ton of time and investment, to get good at cold email, and these reviews are what makes it all worth it. It validates that all the 100 hour weeks, and hundreds of thousands of dollars invested into cold.email all worth it.

I met John Tanner the owner in early January. His energy, competence, and transparency in showing me how cold email, lead generation, Clay expertise.. transformed my thinking and inspired me to great a new business.

I did consulting with him via Upwork and he initially did not charge me to speak with me for almost 2 hours.

There are many people promising big things with cold email but this guy really knows his STUFF!

Highly recommend.

Can't argue with results

I met with at least 4 different companies that promised great results with cold email and ended up picking the most expensive option--cold.email--and we are glad we did. We ended up going with John Tanner Worthington and cold.email because of the confidence he instilled in the potential of our campaign and the robust systems that are part of the offering (Clay and Instantly softwares at the core).

We launched the campaign recently and the results have been solid. We are getting deals signed pretty much every day from the cold email leads...and I don't think we have seen the full potential of the campaign yet. Still a lot of honing in, refining, and adjusting to get it just right. Hiring John Tanner Worthington was a good business decision for us.

Hey Tyler,

I really appreciate you taking the leap of faith and going with us. We invest very heavily in our team, software, and systems to deliver a quality that surpasses all our competitors. While this does drive up the price, we have seen the investment is well worth it if you have good product market fit and are really ready to take on a lot of leads.

I look forward to continue generating businesses for your firm Tyler.

Tanner Market System Striker

Okay so here's how the rest of people and I think about doing cold email. Do the technical setup --> follow a generic email copy --> get a list from apollo & blast it to a bunch of businesses without having any understanding of who are we reaching out and why.

If you follow traditional route like how I did and received 70 positive replies out of 100K email I have sent. You will encounter, most don't have the budget, some will ghost you because you don't really have a reason to connect and address their concern through personalization, some are just there to explore your services as an option & you will end up making 1 sale.

Here's what I absolutely love about John Tanner, he build this innovative system from the ground up to resolve this problem, he's not another internet guru who is trying to hit 10K a month. The enrichment and crazy customized filters make this process super qualified, targeted, efficient...industry standards is to book 1 appointment per 1K email but John can get you 10X more with the same number of emails. I love everything he has taught me. all this being said, he's on the top of this game, just go for him when it comes to cold email because he don't just try to pitch you his services, but actually help and resolve your problems with your lead generation.

Hey Edris,

I really appreciate how well you were able to describe our values.

I have seen time and time again of failed agency owners turning into internet gurus and selling a lifestyle and a course.

I think learning should be free and so I go out of my way to create production level quality content on my youtube channel.

We get hundreds of inbound opportunities a month, and we don't have the capacity to help every single person. I really appreciate all the kind words and hope more people can find my youtube channel under "John Tanner Worthington" and get the help they need.
