Forever free email tools for marketing and sales (by Email Dive)

Forever free email tools for marketing and sales

Here’s a collection of the best free tools for people who send emails for work. Created by Email Dive. Created for anyone marketing or selling through email.

Each one does one job, works in your browser, and lets you leave the second you’re done. I build them for Email Dive readers, but anyone can use them. You don’t have to read a single review first. You don’t even have to like me (but it would be great if you do ☺️).

The tools

There are two right now, an SPF checker and an email signature generator, with more on the way.

Free SPF checker

Checks your domain’s SPF record and tells you what’s wrong with it: syntax errors, more than 10 DNS lookups, broken includes, a second SPF record that shouldn’t exist, or an ending that trusts way too many people. You get a breakdown of your SPF policy, the full lookup path, and what to fix. Which beats finding out from your open rates.

Good for: anyone who just connected one more email tool to their domain and now has a quiet, creeping feeling that something broke.

Free email signature generator

Builds a clean HTML email signature you can paste into Gmail, Outlook, Apple Mail, or Thunderbird. Pick one of six layouts and six accent colors, add your photo and up to eight social profiles, and copy the whole thing in one click. There’s no watermark on the result, which, weirdly, is rare for a free signature tool.

Good for: anyone whose current signature is just their name and a phone number they stopped answering a while ago.

Why they’re free

They’re free because the tools aren’t the business. Email Dive reviews email marketing and sales software, and when you buy something through some of the links in those reviews, I earn a commission. That’s how the lights stay on. The tools don’t sell you anything. They just sit here being useful.

And a lot of “free” tools in this space aren’t really free. They want your email first, or they stamp their logo on whatever you made, or they cut you off after three uses and show you a pricing page. You’ve seen it. I’ve seen it. Everybody’s a little tired.

Who they’re for

Email Dive readers first, because that’s who I’m thinking about when I build them. But they’re for anyone who sends email for work: marketers, salespeople, freelancers, founders, and the one person at a small company who somehow ended up in charge of “the email stuff.” You know who you are.
