How to Self-Host Mautic on a VPS: Email Marketing Automation Without Monthly Fees

Mautic is the leading open-source marketing automation platform — it handles email campaigns, lead scoring, drip sequences, landing pages, form capture, contact segmentation, and A/B testing. Mailchimp charges $35–$350/month depending on list size. Self-hosting Mautic on a VPS eliminates the per-contact billing entirely — you pay only for your VPS and your email delivery service (SendGrid, Amazon SES, or Mailgun charge fractions of a cent per email).

What Mautic Provides

• Email campaigns: One-time broadcast emails to segmented contact lists
• Drip campaigns: Automated sequences triggered by actions or time intervals
• Contact management: Import, segment, tag, and score contacts
• Lead capture: Embedded forms, landing pages, and website tracking
• A/B testing: Subject line and content variants with statistical comparison
• CRM integration: Sync with Salesforce, HubSpot, SugarCRM via plugins

Server Requirements

• Minimum 2 GB RAM (4 GB recommended for active campaigns)
• PHP 8.1–8.2, Apache or Nginx, MariaDB or MySQL
• A domain with proper SPF, DKIM, and DMARC records
• An external transactional email service (SendGrid, SES, or Mailgun) for deliverability

Step 1: Install LAMP Stack

<code">sudo apt update && sudo apt upgrade -y

sudo apt install -y apache2 mariadb-server php8.2 php8.2-fpm \
  php8.2-mysql php8.2-xml php8.2-curl php8.2-gd php8.2-mbstring \
  php8.2-zip php8.2-imap php8.2-intl php8.2-bcmath php8.2-apcu \
  libapache2-mod-php8.2 unzip git

# Enable Apache modules
sudo a2enmod rewrite ssl headers php8.2

sudo systemctl enable apache2 mariadb

Step 2: Configure PHP for Mautic

<code">sudo nano /etc/php/8.2/apache2/php.ini

<code">memory_limit = 512M
upload_max_filesize = 64M
post_max_size = 64M
max_execution_time = 300
date.timezone = UTC

; OPcache
opcache.enable = 1
opcache.memory_consumption = 128

Step 3: Create Database

<code">sudo mysql -u root

<code">CREATE DATABASE mautic CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
CREATE USER 'mautic'@'localhost' IDENTIFIED BY 'StrongMauticPassword!';
GRANT ALL PRIVILEGES ON mautic.* TO 'mautic'@'localhost';
FLUSH PRIVILEGES;
EXIT;

Step 4: Download Mautic

<code"># Download latest Mautic release
cd /var/www
sudo wget https://github.com/mautic/mautic/releases/download/5.1.1/mautic-5.1.1.zip
sudo unzip mautic-5.1.1.zip -d mautic
sudo rm mautic-5.1.1.zip
sudo chown -R www-data:www-data /var/www/mautic

Step 5: Apache Virtual Host

<code">sudo nano /etc/apache2/sites-available/mautic.conf

<code"><VirtualHost *:80>
    ServerName mautic.yourdomain.com
    Redirect permanent / https://mautic.yourdomain.com/
</VirtualHost>

<VirtualHost *:443>
    ServerName mautic.yourdomain.com
    DocumentRoot /var/www/mautic

    SSLEngine on
    SSLCertificateFile /etc/letsencrypt/live/mautic.yourdomain.com/fullchain.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/mautic.yourdomain.com/privkey.pem

    <Directory /var/www/mautic>
        Options -Indexes +FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/mautic_error.log
    CustomLog ${APACHE_LOG_DIR}/mautic_access.log combined
</VirtualHost>

<code">sudo a2ensite mautic
sudo a2dissite 000-default
sudo nginx -t 2>/dev/null; sudo apachectl configtest
sudo systemctl reload apache2
sudo certbot --apache -d mautic.yourdomain.com

Step 6: Web Installer

1. Visit https://mautic.yourdomain.com
2. Follow the installation wizard — enter database credentials
3. Create your admin account
4. Complete the setup wizard

Step 7: Configure Transactional Email Sending

Never send marketing email from your VPS’s local mail server — you’ll be blacklisted. Use a transactional email service:

In Mautic Admin → Settings → Configuration → Email Settings:

<code"># SendGrid configuration:
Mailer Transport: Sendgrid API
Sendgrid API Key: SG.your_api_key_here

# OR Amazon SES (SMTP):
Mailer Transport: SMTP
SMTP Host: email-smtp.us-east-1.amazonaws.com
SMTP Port: 587
SMTP Security: TLS
Username: AKIAIOSFODNN7EXAMPLE
Password: your_ses_smtp_password

Step 8: Set Up Cron Jobs (Critical)

Mautic relies on cron jobs for sending emails, processing contacts, and running automations. Without these, nothing sends:

<code">sudo crontab -u www-data -e

<code"># Process email queue and send campaigns (every 5 minutes)
*/5 * * * * php /var/www/mautic/bin/console mautic:emails:send >> /var/log/mautic-cron.log 2>&1

# Process campaign actions (every 5 minutes)
*/5 * * * * php /var/www/mautic/bin/console mautic:campaigns:trigger >> /var/log/mautic-cron.log 2>&1

# Update contact segments (every 15 minutes)
*/15 * * * * php /var/www/mautic/bin/console mautic:segments:update >> /var/log/mautic-cron.log 2>&1

# Process webhooks (every minute)
* * * * * php /var/www/mautic/bin/console mautic:webhooks:process >> /var/log/mautic-cron.log 2>&1

# Social monitoring (hourly)
0 * * * * php /var/www/mautic/bin/console mautic:social:monitoring >> /var/log/mautic-cron.log 2>&1

Step 9: Email Authentication (SPF, DKIM, DMARC)

Without proper email authentication, campaigns go to spam. Configure at your DNS provider:

<code"># SPF record
yourdomain.com    TXT    "v=spf1 include:sendgrid.net ~all"

# DKIM (provided by your email service — copy from their DNS settings)
s1._domainkey.yourdomain.com    TXT    "v=DKIM1; k=rsa; p=MIGfMA0..."

# DMARC
_dmarc.yourdomain.com    TXT    "v=DMARC1; p=quarantine; pct=100; rua=mailto:dmarc@yourdomain.com"

Getting Started

Mautic requires 2 GB RAM minimum; 4 GB is recommended for lists over 10,000 contacts with active automations. Ubuntu VPS plans at VPS.DO with NVMe storage handle Mautic’s database queries efficiently. For organizations currently paying $100+/month for Mailchimp or ActiveCampaign, self-hosted Mautic on a $20/month VPS plus $10–$50/month for email delivery (Amazon SES at $0.10/1,000 emails) reduces marketing infrastructure cost by 80%.

Conclusion

Self-hosted Mautic delivers enterprise marketing automation features — email campaigns, drip sequences, contact scoring, A/B testing, and CRM integration — at VPS cost plus email delivery fees. The cost advantage over SaaS alternatives grows with list size: Mautic’s cost doesn’t increase with contacts, only with the VPS plan needed to handle the database and queue volume. Configure cron jobs correctly and use a reputable transactional email service for reliable delivery.
