Has anyone set up language based personalization in tools like Smartlead or Instantly where emails auto-adjust to the prospect’s language in email/LinkedIn campaigns? You guys did something like this before?

We use our tool (underfive) to manage language-based replies. After an initial outbound message is sent through any sequencer, the conversation automatically continues in the recipient’s language once a reply is received, helping to book meetings.

Yes, this is usually done in Clay first by detecting the prospect’s language from their profile or website, then passing it as a variable into Smartlead/Instantly so the right copy is used automatically. I can help you set this up properly. Are you currently detecting language or just relying on country data? Donnel C.

No it’s just a question I thought about since I’m in my journey a GTM role and wanted to hear perspectives from persons in the space.
