Automated Synology C2 Renewal Reminders

Every morning, WebRun opens Synology C2, checks the plan renewal date and current storage usage, logs it as a row in Google Sheets, and emails you a reminder through Gmail once renewal is within 5 days.

In short

How do I get reminded before my Synology C2 plan renews?

WebRun checks your Synology C2 account every morning for the plan renewal date, storage usage, and price, logging each check as a row in Google Sheets. Once renewal is within 5 days, it emails you a reminder through Gmail, so a backup storage plan never lapses without you seeing it coming.

  • Renewal dates tracked daily without checking C2 yourself
  • A running usage and renewal history in one sheet
  • Reminder emails only when the date is genuinely close

Questions, answered

Will it renew the plan or charge my card?

No. WebRun only reads the renewal date and reminds you. Renewing or changing your plan happens directly in Synology C2.

Why log it to a sheet as well as email me?

The sheet keeps a running history of usage and renewal checks, while the email is reserved for when the date is genuinely close.

What if I already renewed?

It reads the live renewal date each morning, so once you renew, the reminder emails stop on their own.

Put this on autopilot.
