How AI variables make personalized outreach a breeze
Reply.io now has AI Variables to tackle some of the biggest pain points in cold outreach—like personalizing emails at scale without burning out!
This feature is ideal for those who want to stay in control and aren’t quite ready to rely entirely on AI. Rather than customizing each message by hand, you can create a single email template with AI variables that automatically generate personalized content based on your prompt.
Save time, reduce the risk of sounding robotic, and increase your chances of getting a response—all while scaling your outreach efforts like a pro!
For example, instead of writing separate emails to each prospect, you write one email like this:

So, how does it work?
- Start by preparing an enriched list of contacts. You can either find relevant contacts using Reply Real-Time data or enhance your existing list with the Reply Enrichment feature.
- Next, create a sequence for these contacts, just like you normally would.
- When you’re writing an email—whether manually or with Jason AI—simply place your cursor where you want to add the AI variable.
- Click the AI Variable icon and write your prompt.
- To personalize your messages, use standard variables within your prompt. The AI will then craft a unique message for each prospect based on the details you provide.
- You’ll be able to preview the result immediately and tweak it if needed.
- You can also see the message preview for each contact in the Preview tab and make any edits to ensure everything looks perfect.
Easy, right? But we didn’t stop there.
We’ve also created a library of proven prompts to make things even simpler and help you get started quickly. Once you get the hang of it, you can create your own prompts and save them in the library as personal ones. You can easily search for and reuse them whenever you need.

Now, everything you need for perfect outreach is all in one place—no more relying on third-party tools for lead generation, lead enrichment, personalization, or multichannel outreach. Pretty great, right?
