8 Totally Free Email Marketing Tools for Your Business

We love building tools for email marketers. SendView was the first one that solved the big, hairy problem of competitor email tracking, but we've also built a (growing) collection of free tools as well for folks like you. These tools are totally free to use and cover a long list of use cases including discovering which tech email marketers are using to snagging screenshots of your favorite campaigns. Browse our list below and, if you have an idea for another email marketing tool, just let us know! We're always looking to add to this list.

2) EML Viewer

EML files are notorious for being hard to decipher within a text editor, so we built a little tool that parses out the headers into a cleaner format and decodes the contents into traditional text or HTML formats. You can view all of the details of each line in the headers, you can view the raw email HTML, decoded email HTML, raw plain text, decoded plain text, and even the AMP details if they're using a marketing tool that allows them to use AMP script.

This tool contains a few handy features including:

• See all of the email's headers broken down into an easy-to-read table
• View the raw and decoded version of the email's plain text contents
• View the raw and decoded version of the email's HTML contents
• If included, view the AMP script version of the email

3) Email Tech Tracker

Curious how many people use dark mode? Sign with DKIM? Use Gmail Annotations? Email Tech Tracker analyzes the high level trends from SendView data to answer those very questions. This free marketing tool allows you to track how many emails each month use various types of email code, tools, or strategy so you can understand if you're one of a few who aren't using a new bit of tech or you're in the majority.

This tool includes the following features:

• The most recent month's stats for each email insight
• A six month trend graph for each email stat

6) Mailto Link Generator

We're email people, so while mailto links aren't as popular as they once were we think they're an underappreciated feature of email. So we build a tool to make it easy to create these links. This tool allows you to include all of the available fields including to address, CC, BCC, subject line, and body. Like some of our other email tools, this tool will automatically generate the link as you type in the details.

Popular features of the mailto tool are:

• Real-time generation of email links as you fill out the inputs

The first version of this email tool allows you to generate a full-length screenshot at a fixed width, but as this tool gains popularity we're looking and adding advanced screenshot options and settings.

This tool is simple, but the main features are:

8) Gmail Annotations Builder

Gmail Annotations can be a powerful ally, but they can be tough to integrate into a campaign.
