SMTP Configuration

Use Quolle as an SMTP relay from any framework, CMS, or no-code tool that supports SMTP — no SDK installation required.

SMTP credentials

Use these settings in any application that asks for an SMTP server:

Laravel

Add these to your .env file:

MAIL_MAILER=smtp
MAIL_HOST=smtp.quolle.com
MAIL_PORT=587
MAIL_USERNAME=qle_your_api_key
MAIL_PASSWORD=qle_your_api_key
MAIL_ENCRYPTION=tls
MAIL_FROM_ADDRESS=hello@mail.yourdomain.com
MAIL_FROM_NAME="${APP_NAME}"

Then send mail as usual with Laravel's Mail facade:

Mail::to('customer@example.com')->send(new WelcomeMail());

Django

Add to your settings.py:

EMAIL_BACKEND  = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST     = 'smtp.quolle.com'
EMAIL_PORT     = 587
EMAIL_USE_TLS  = True
EMAIL_HOST_USER     = 'qle_your_api_key'
EMAIL_HOST_PASSWORD = 'qle_your_api_key'
DEFAULT_FROM_EMAIL  = 'hello@mail.yourdomain.com'

Send emails using Django's built-in send_mail:

from django.core.mail import send_mail

send_mail(
    subject='Welcome!',
    message='Thanks for signing up.',
    from_email='hello@mail.yourdomain.com',
    recipient_list=['customer@example.com'],
    html_message='<h1>Welcome!</h1>',
)

Nodemailer (Node.js)

import nodemailer from "nodemailer";

const transporter = nodemailer.createTransport({
  host: "smtp.quolle.com",
  port: 587,
  secure: false, // STARTTLS — do NOT use port 465
  auth: {
    user: "qle_your_api_key",
    pass: "qle_your_api_key",
  },
});

await transporter.sendMail({
  from: '"Acme" <hello@mail.yourdomain.com>',
  to: "customer@example.com",
  subject: "Welcome!",
  html: "<h1>Welcome to Acme</h1>",
});

WordPress (WP Mail SMTP)

Install the free WP Mail SMTP plugin, then configure under Settings → WP Mail SMTP → General:

1. Set Mailer to Other SMTP
2. SMTP Host: smtp.quolle.com
3. SMTP Port: 587
4. Encryption: TLS (STARTTLS)
5. Auto TLS: On
6. Authentication: On
7. SMTP Username: your API key (qle_…)
8. SMTP Password: your API key (same value)
9. From Email: your verified address, e.g. noreply@mail.yourdomain.com
10. Save and use Email Test to confirm delivery

Bubble.io

In your Bubble app, go to Settings → Email:

1. Enable Use a custom email provider
2. Email address: your verified address
3. Click Configure and enter the SMTP settings above
4. Bubble uses these credentials for all system emails and workflow email actions

config.action_mailer.smtp_settings = {
  address:              'smtp.quolle.com',
  port:                 587,
  domain:               'yourdomain.com',
