What Is BillionMail?

BillionMail is an all-in-one, open-source platform for managing email campaigns, newsletters, and transactional emails.

Why BillionMail Stands Out

What makes BillionMail a must-have for email marketing? Here’s the rundown:

  • Advanced Analytics: Dive into delivery rates, open rates, and click-throughs to fine-tune your campaigns.
  • Unlimited Sending: No limits on email volume—perfect for newsletters or massive promotions.
  • Customizable Templates: Create and reuse professional designs that align with your brand.
  • Privacy-Centric: Keep your data secure on your own server.
  • Smart Customer Management: Organize lists, tags, and segments for pinpoint targeting.
  • Easy Domain Setup: Auto-SSL and DNS verification streamline the process.

These features tackle the pain points of costly, rigid platforms, giving you unmatched freedom.

Get Started in Just 3 Steps

BillionMail makes it ridiculously easy to get up and running—think 8 minutes from install to sending your first email. Here’s how:

Step 1: Install BillionMail

Pop open your terminal and run:

cd /opt && git clone https://github.com/aaPanel/BillionMail && cd BillionMail && bash install.sh

Prefer Docker? Use this:

cd /opt && git clone https://github.com/aaPanel/BillionMail && cd BillionMail && cp env_init .env && docker compose up -d || docker-compose up -d

On aaPanel? Just hit the one-click install in the Docker section.

Step 2: Connect Your Domain

  • Add your sending domain.
  • Verify DNS records.
  • Let BillionMail set up free SSL automatically.

Step 3: Build Your Campaign

  • Write or paste your email content.
  • Select your audience with lists and tags.
  • Send now or schedule it for later.

Managing it is a breeze with commands like bm help for guidance, bm default for login info, bm show-record for DNS details, and bm update to keep things fresh.

Why Choose BillionMail Over Paid Platforms?

Big-name platforms like Mailchimp or Sendinblue often come with steep costs and rigid ecosystems. BillionMail breaks the mold:

  • Zero Cost, Total Freedom: Licensed under AGPLv3, it’s free to use, modify, and distribute.
  • Developer-Friendly: Open-source on GitHub, ready for your customizations.
  • Full Control: Self-hosting means you own your data and scale as you please.
