Newsletter & Subscribe Page
How the public subscribe page works with GDPR double opt-in and confirmation emails.
How It Works
The newsletter system captures leads from your marketing website and adds them to your contact database.
When someone subscribes via the TempClock website, the following happens automatically:
Double Opt-In Flow
GDPR-compliant two-step verification.
User fills in the form
The visitor enters their email address and ticks the consent checkbox. Their record is created with confirmed = 0 and subscribed = 0.
Confirmation email sent
An email is sent immediately with a unique, HMAC-signed confirmation link. This link cannot be guessed or tampered with.
User confirms
When the user clicks the link, their record is updated to confirmed = 1 and subscribed = 1. They are now eligible to receive campaigns.
Contacts who have not confirmed cannot receive campaigns. This protects you from sending unsolicited emails and ensures GDPR compliance.
Where Users Can Sign Up
Multiple lead capture points across the website.
Dedicated page at tempclock.com/subscribe.php with full form (email, name, company, consent checkbox)
Compact email-only signup in the website footer — appears on every page
Optional newsletter opt-in checkbox on the contact page — checked by default
Newsletter signup sections embedded on key pages like the homepage and pricing page
All signup points use the same backend and double opt-in process. The source field tracks where each contact signed up (e.g. "footer", "contact_form", "homepage").
Unsubscribe Process
One-click removal from all campaigns.
Every campaign email includes an unsubscribe link at the bottom. When clicked:
subscribed field is set to 0 and unsubscribed_at is timestamped
The unsubscribe page shows a confirmation message. The contact can re-subscribe at any time by visiting the subscribe page again.
