Email Service

Every cloud function has access to a fully managed email service. No setup required — just use the email global and Cocobase handles the rest.

​
Provider Priority

Cocobase automatically selects the best available email provider for your project:
  1. Project Integration (CocoMailer / Resend / EmailJS)
  2. SMTP Configuration (your own SMTP server)
  3. Cocobase Fallback (managed Resend via noreply@cocobase.buzz)
Configure your preferred provider once in the dashboard and all email calls use it automatically.

​
Two Ways to Send Email

​
1. req.send_mail() — Quick Send

Best for simple one-off emails: 
def main():
    req.send_mail(
        to="user@example.com",
        subject="Hello!",
        body="<p>Welcome to our platform.</p>"
    )
    return {"sent": True}
ParameterTypeRequiredDescription
tostr or list✅Recipient(s)
subjectstr✅Email subject
bodystr❌HTML body
template_idstr❌Template name to use
contextdict❌Template variables

​
2. email.* — Full Email Service

The email global is pre-injected into every cloud function — no imports needed.

​
Email Methods

​
Send Generic Email

def main():
    await email.send_email(
        recipients=["alice@example.com", "bob@example.com"],
        subject="Your order is confirmed",
        body="<h1>Thanks for your order!</h1>"
    )
    return {"ok": True}

​
Send Welcome Email

def main():
    await email.send_welcome_email(
        to_email="user@example.com",
        user_name="John",
        app_name="MyApp",
        login_url="https://myapp.com/login"
    )
    return {"registered": True}

​
Send Password Reset Email

def main():
    user_email = req.get("email")
    token = secrets.token_urlsafe(32)

    db.create_document("password_resets", {
        "email": user_email,
        "token": token
    })

    await email.send_password_reset_email(
        to_email=user_email,
        token=token,
        reset_url_base="https://myapp.com/reset-password",
        app_name="MyApp",
        expiry_hours=2
    )
    return {"reset_email_sent": True}

​
Send Password Changed Confirmation

def main():
    user = req.user
    if not user:
        return {"error": "Unauthorized"}, 401

    await email.send_password_changed_email(
        to_email=user.email,
        app_name="MyApp"
    )
    return {"password_updated": True}

​
Send 2FA Code Email

def main():
    user_email = req.get("email")
    code = "".join([str(secrets.randbelow(10)) for _ in range(6)])

    db.create_document("otp_codes", {
        "email": user_email,
        "code": code
    })

    await email.send_2fa_code_email(
        to_email=user_email,
        code=code,
        app_name="MyApp",
        expiry_minutes=10
    )
    return {"otp_sent": True}

​
Error Handling

def main():
    try:
        await email.send_password_reset_email(
            to_email=req.get("email"),
            token=reset_token,
            app_name="MyApp"
        )
        return {"sent": True}
    except Exception as e:
        print(f"Email failed: {e}")
        return {"error": "Could not send email"}, 500
Note: send_welcome_email silently suppresses errors so registration is never blocked. All other methods raise on failure — always wrap in try/except.

​
Email Logging

Every email sent is automatically logged in your dashboard under Email → Logs. Each entry records recipients, subject, template used, status (PENDING → SENT or FAILED), and timestamp.
