ExtendSync gives users full control over how emails are attached to NetSuite.
This guide explains the differences between One-Time Save, Thread-Based Autopilot, and Email Address-Based Autopilot and when to use each one for best results.
🎥 Watch the video or continue reading below to learn how and when to use each method effectively.
🧠 First Things First
Just because it’s easy to add emails to NetSuite doesn’t mean every email belongs there.
Before attaching an email, ask yourself:
“Will this information be helpful to others in the organization?”
If the answer is yes — save it.
If not — leave it out to avoid unnecessary clutter.
One-Time method
Attaches one specific email to a NetSuite record.
Ideal for isolated conversations or emails you don’t need future replies for.
Gives you full manual control over which emails are visible in NetSuite.
✅ Example Use Case:
A customer sends a one-time inquiry about an invoice, and you want to log that single email to their record without syncing the full reply chain.
Autopilot for Emails
Thread-based Autopilot
Automatically syncs all future replies and responses in an email thread.
Best for transaction-based records that are time-bound, such as:
Estimates
Opportunities
Sales Orders
Keeps related communication organized under one record without syncing unrelated messages.
✅ Example Use Case:
A sales rep is negotiating an opportunity with multiple follow-up replies. Thread-based Autopilot ensures every related message stays attached to that Opportunity record.
Email Address-Based Autopilot
Tracks and syncs all emails to/from a specific address to selected NetSuite records — automatically.
Best for entity-level records (Customers, Contacts, Leads, Prospects).
Ideal for long-term relationships where every email is relevant to the account.
Email Address based Autopilot (To/From/CC) functionality is limited to the primary folder and the sent folder in your Outlook.
✅ Example Use Case:
A prime example of how we use email Autopilot at CloudExtend lies with our Customer Success team. For each subscription, there is a primary customer contact. That contact’s email address is on email Autopilot ensuring every conversation automatically appears in NetSuite — even if handled by different CSMs over time.
⚠️ Caution:
Be selective when enabling Email Address–Based Autopilot. Every email exchanged with that address even unrelated ones will sync to NetSuite.
Things to Avoid
❌ Avoid This | 💡 Why |
Adding your own email address or a colleague’s email address to Autopilot | This will cause all internal messages to sync to the same record(s). |
Enabling Autopilot without reviewing the record | Ensure that the record type is appropriate (e.g., Customers for address-based, Opportunities for thread-based). |
