AI chatbots are already being used to send custom email pitches. It shows how AI like ChatGPT may soon play a significant role in business, with companies like Salesforce and Microsoft beginning to offer tighter integration between the chatbot and their software.
A recent viral Tiktok showed how it’s possible to use ChatGPT integrated with Google Sheets to write ten custom LinkedIn messages to executives asking for a meeting. It identified different potential companies in an industry and their CEOs, and generated different outreach notes for each one, including a unique question to ask.

“I think we’re at a very interesting inflection point of how we’ll begin to use AI in the future in our day-to-day lives that wasn’t as easily accessible even six months ago, before ChatGPT was more readily available to the public,” said Alex Klufas, a creator who makes videos focused on working in the tech industry.
The video — and previous viral posts displaying similar techniques — clearly struck a nerve, with 2.5 million views, and scores of comments asking how it worked.
Generative AI and tools using large language model (LLM) techniques like ChatGPT have led to a boom as big tech companies and startups alike race to integrate software capable of producing content that resembles something a human would write.
Few LLM-based products are actually making money. Microsoft and Google are working to integrate next-level chatbots into search engines. Companies are working on using these bots to write marketing copy or computer code.
There’s one particularly promising application that could be commercialized in the near future: Using the power of a chatbot to quickly write and automate emails with a little bit of personalization, perhaps for sales, marketing, or personal networking. Microsoft and Salesforce announced new products this week with that exact feature.
Financial analysts at Credit Suisse pointed to email generation several times in a note earlier this month as a concrete and near-term use for the technology. The analysts estimated Microsoft’s recently announced generated AI sales features could help it take market share and potentially add over $768 million in annual revenue.
Products coming to market
On Tuesday, Salesforce announced its LLM product called EinsteinGPT, which uses an OpenAI ChatGPT model. It can automatically write marketing emails — a logical integration because Salesforce’s main product is a web app that keeps track of how often salespeople contact leads.
In a tweet on Tuesday, Salesforce CEO Marc Benioff demoed the software, using it to identify two contacts at a company, then automatically generating a one-sentence email trying to arrange a meeting. In the demo, EinsteinGPT softened the cold outreach email after the user told the software to be less formal.
Salesforce hasn’t set a price for the tools yet but said it’s in testing now with pilot customers.
Microsoft announced on Monday that it would integrate generative AI based on ChatGPT into a set of tools for business called CoPilot. One of its primary features is using AI to generate emails.
In a demo video, Microsoft showed the feature integrated into an Outlook mailbox and provided examples of using it to reply to a request for proposal, or to suggest a meeting time with a customer.
In the example, an inbound email wanted to follow up on a potential sales deal, and Microsoft’s feature offered four different draft replies, including one that offered a discount and another that addressed a concern.
Microsoft says that its AI email writer can take important context from the email thread, like the price that was previously discussed, and stick it in the response drafted by AI. In the example provided by Microsoft, the user takes the AI draft and edits it before sending it.
Microsoft’s feature is currently in beta testing, but will be released to customers of Microsoft’s Viva Sales feature on March 15, the company said on Monday.
Some startups have even trained their sights on developing customized AIs that can respond to messages the same way that their owner would, by analyzing a user’s previous email and text interactions and integrating it into a personalized AI model.
“The benefit is people who would want to communicate with you where you don’t have time to get back to them, where you don’t have time to offer your mind,” said Suman Kanuganti, founder of personal.ai, a chatbot currently in beta mode. “In those scenarios, you can choose to either have your AI help you in co-pilot mode or offer [automatic] responses to them in autopilot mode.”
Shortcomings
Some worry that the ability to generate email text could be abused to spam people and that chatbots could be used to phish for people’s private passwords.
“We could see mass targeted messages and spam indistinguishable from dedicated email,” JPMorgan analysts wrote in a note this month that examined the AI industry.
ChatGPT is also prone to “hallucinating,” or making stuff up. It merely predicts what the next word or part of a phrase should be based on statistics, and doesn’t know whether it’s correct or not.
Microsoft said in its announcement that it would use data from its software to ground the replies in facts, and has a thumbs-down button so users can tell the bot that a response was unhelpful. That helps train the model to avoid the same mistake in the future. A Salesforce executive previously told CNBC that it was moving as quickly as it could without compromising a responsible, ethical approach.
But the limits of ChatGPT were clearly visible in the viral TikTok video. While some recommendations were correct, several of the CEOs ChatGPT recommended for outreach were either former CEOs or are not currently an executive at the company. While the text for the cold outreach looked appropriate, it would still likely require a human to make sure everything was actually right.
“I think anyone using this technology, as nascent as it is, has to do that due diligence,” Kluflas said. She didn’t end up sending the notes generated by ChatGPT because she’s not currently looking for a job.
But she’s still excited about using ChatGPT to help her make TikToks and other content for social media. Her latest application is to use ChatGPT to produce TikTok captions packed with the keywords that make her videos easier to find online.

Hims & Hers Health shares closed up 5% on Tuesday after the company announced patients can access Eli Lilly‘s weight loss medication Zepbound and diabetes drug Mounjaro, as well as the generic injection liraglutide, through its platform.
Zepbound, Mounjaro and liraglutide are part of the class of weight loss medications called GLP-1s, which have exploded in popularity in recent years. Hims & Hers launched a weight loss program in late 2023, but its GLP-1 offerings have evolved as the company has contended with a volatile supply and regulatory environment.
Lilly’s weekly injections Zepbound and Mounjaro will cost patients $1,899 a month, according to the Hims & Hers website. The generic liraglutide will cost $299 a month, but it requires a daily injection and can be less effective than other GLP-1 medications.
“As we look ahead, we plan to continue to expand our weight loss offering to deliver an even more holistic, personalized experience,” Dr. Craig Primack, senior vice president of weight loss at Hims & Hers, wrote in a blog post.
A Lilly spokesperson said in a statement that the company has “no affiliation” with Hims & Hers and noted that Zepbound is available at lower costs for people who are insured for the product or for those who buy directly from the company.
In May, Hims & Hers started prescribing compounded semaglutide, the active ingredient in Novo Nordisk‘s GLP-1 weight loss medications Ozempic and Wegovy. The offering was immensely popular and helped generate more than $225 million in revenue for the company in 2024.
But compounded drugs can traditionally only be mass produced when the branded medications treatments are in shortage. The U.S. Food and Drug Administration announced in February that the shortage of semaglutide injections products had been resolved.
That meant Hims & Hers had to largely stop offering the compounded medications, though some consumers may still be able to access personalized doses if it’s clinically applicable.
During the company’s quarterly call with investors in February, Hims & Hers said its weight loss offerings will primarily consist of its oral medications and liraglutide. The company said it expects its weight loss offerings to generate at least $725 million in annual revenue, excluding contributions from compounded semaglutide.
But the company is still lobbying for compounded medications. A pop up on Hims & Hers’ website, which was viewed by CNBC, encourages users to “use your voice” and urge Congress and the FDA to preserve access to compounded treatments.
With Tuesday’s rally, Hims and Hers shares are up about 27% in 2025 after soaring 172% last year.

Meta’s head of artificial intelligence research announced Tuesday that she will be leaving the company.
Joelle Pineau, the company’s vice president of AI research, announced her departure in a LinkedIn post, saying her last day at the social media company will be May 30.
Her departure comes at a challenging time for Meta. CEO Mark Zuckerberg has made AI a top priority, investing billions of dollars in an effort to become the market leader ahead of rivals like OpenAI and Google.
Zuckerberg has said that it is his goal for Meta to build an AI assistant with more than 1 billion users and artificial general intelligence, which is a term used to describe computers that can think and take actions comparable to humans.
“As the world undergoes significant change, as the race for AI accelerates, and as Meta prepares for its next chapter, it is time to create space for others to pursue the work,” Pineau wrote. “I will be cheering from the sidelines, knowing that you have all the ingredients needed to build the best AI systems in the world, and to responsibly bring them into the lives of billions of people.”

Pineau was one of Meta’s top AI researchers and led the company’s fundamental AI research unit, or FAIR, since 2023. There, she oversaw the company’s cutting-edge computer science-related studies, some of which are eventually incorporated into the company’s core apps.
She joined the company in 2017 to lead Meta’s Montreal AI research lab. Pineau is also a computer science professor at McGill University, where she is a co-director of its reasoning and learning lab.
Some of the projects Pineau helped oversee include Meta’s open-source Llama family of AI models and other technologies like the PyTorch software for AI developers.
Pineau’s departure announcement comes a few weeks ahead of Meta’s LlamaCon AI conference on April 29. There, the company is expected to detail its latest version of Llama. Meta Chief Product Officer Chris Cox, to whom Pineau reported to, said in March that Llama 4 will help power AI agents, the latest craze in generative AI. The company is also expected to announce a standalone app for its Meta AI chatbot, CNBC reported in February.
“We thank Joelle for her leadership of FAIR,” a Meta spokesperson said in a statement. “She’s been an important voice for Open Source and helped push breakthroughs to advance our products and the science behind them.”
Pineau did not reveal her next role but said she “will be taking some time to observe and to reflect, before jumping into a new adventure.”
