Great observation! What you're likely seeing is automated link clicks from email security scanners, not real human clicks. Here's what happens:

• Many email providers (especially corporate ones using Microsoft Defender, Barracuda, Mimecast, etc.) automatically follow every link in an incoming email to check for malware or phishing
• This happens instantly upon delivery, before the recipient even opens the email
• It registers as a legitimate click in tracking systems like SendGrid

A few telltale signs this is what's happening:
- The clicks appear within seconds or a minute of delivery
- Multiple links in the same email are clicked at the same time
- It tends to happen with recipients at companies using enterprise email security

This is a known limitation of email click tracking in general, not unique to Decile Hub. Unfortunately there's no perfect fix since these scanners behave like real browsers.

That said, I'll flag this to the team so they can look into whether there's anything that can be done on Decile's end to help filter out bot clicks from your newsletter analytics. Thanks for raising it!
