1. Install Mautic Email Marketing Application
Mautic is a brilliant open-source marketing automation software widely used as a self-hosted email marketing solution. Yes, you’ll host the Mautic application on your server.
You need two things to use Mautic:
- VPS Server
- Domain Name
Go get the VPS hosting from top providers like DigitalOcean or Contabo. And then get the domain name from registrars like GoDaddy or Namecheap if you don’t already have it. Here’s what you need to do:
1. Go to DigitalOcean (Or any other VPS hosting provider)
2. Click on “Create” and then “Droplet”
3. Go to Marketplace and choose ‘LAMP’ as your new droplet.
4. Point your domain or subdomain to VPS using an SSH client like PuTTY.
5. Install Apache, PHP, and MySQL to install Mautic on your VPS hosting. Now go to the WinSCP app and enter your username and password. You’ll see a new Window where you can enter commands.
6. Install Apache2 Web Server on the droplet you’ve just created on DigitalOcean. For that, you need to enter these commands:
sudo apt update
sudo apt install apache2
7. Install MariaDB (MySQL) which is a database server to save your data. Use these commands if you’re on Ubuntu 16 LTS.
sudo apt-get install software-properties-common gnupg-curl
sudo apt-key adv --fetch-keys 'https://mariadb.org/mariadb_release_signing_key.asc'
sudo add-apt-repository 'deb [arch=amd64,arm64,i386,ppc64el] http://mirrors.piconets.webwerks.in/mariadb-mirror/repo/10.5/ubuntu xenial main'
sudo apt update
sudo apt-get install mariadb-server
The database installed? Awesome! Now that you’ve created the Mautic database, download and install Mautic on it.
2. Install SMTP Server in 2021
Postal is a brilliant SMTP server you can use to automate your cold email system. And it needs multiple applications to work as a Simple Mail Transfer Protocol. Install all these frameworks on Ubuntu.
Everything is configured to get your cold email system up and running. You can also hire us to install your Postal SMTP and not worry about any technical stuff in the installation.
3. Connect Mautic With Your SMTP Server

Follow these steps for manual installation of SMTP:

Make Postal admin user using the command : postal make-user
Start Postal using sudo -u postal postal start
After you log in, you’re ready to go.
Go to the credentials tab and create a new credential to use inside Mautic.
