Here’s my hand-picked list of the 12 best cold email automation software:

1. GMass

GMass home page

GMass is a powerful cold email outreach and automation software that works inside Gmail.

Its robust cold emailing capabilities and ease of use make it the go-to cold email tool for salespeople, marketers, small business owners, and even employees at large companies like Google, Uber, and Twitter.

Curious about what GMass offers you?
Let’s find out.

GMass Key Features

Here are five key GMass features that make it perfect for your cold outreach needs:

1. Automatic Email Personalization

Your prospect’s inbox is probably flooded with outreach emails. That’s why sending a generic cold outreach email won’t cut it.

You’ll need to personalize the outreach message based on the prospect’s unique persona and interests. This makes the email relevant to the prospect, improving your chances of receiving a response.

But isn’t personalization time-consuming?
Not when you’re using GMass!

With GMass, you can create an automatically personalized email campaign easily.

2. Bulk Email Scheduling

GMass lets you schedule your cold email to go out at a future time automatically. You can choose from pre-configured dates/times or enter a custom date/time. This way, your email will reach the recipient’s inbox when they’re likeliest to read your email.

Should your plans change, you can quickly reschedule the email from the Gmail “Drafts” folder.

3. Auto Follow-Ups

In most cases, only a few leads will engage with your first cold email.

But that doesn’t mean cold emails are ineffective.

Instead, it means that you need to follow up on your initial conversation — a study reveals that just one additional follow up email can increase your response rate by 65.8%.

However, managing the follow-up process is tedious if you’ve got a long contacts list.

Is there an easier way to follow up with leads?
There is!

In GMass, you can easily set up an automatic workflow to follow up till a potential customer replies.

And the best part is that you can personalize everything about these follow-ups, including the:

  • Follow-up triggers.
  • Number of follow-ups.
  • Time interval between follow-ups, and more.

4. Campaign Analytics Reports

When cold emailing a potential client, there’s no guarantee your emails will work.

But to understand the effectiveness of your cold emails, you’ll need to measure email performance metrics.

Fortunately, every time you send a cold outreach email with GMass, a detailed Campaign Report gets auto-generated in your Gmail inbox.

The report shows crucial metrics like your:

  • Open Rate: Number of unique recipients who opened your cold email.
  • Reply Rate: Number of unique recipients who replied to your cold email.
  • Click Rate: Number of unique recipients who clicked a link inside your cold email.
  • Bounce Rate: Number of cold emails that went undelivered due to invalid addresses.
  • Unsubscribe Rate: Number of recipients who opted out of your cold email campaigns.

Campaign Analytics Reports

5. Email List Builder

Emailing your cold leads one by one is inefficient.

A better approach is to build an email list of your leads and send them a targeted cold email campaign.

But how exactly do you build the email list?

In GMass, building your email list is as simple as doing a Google search. Just head to your Gmail account and search for keywords related to your target audience. GMass will then automatically compile an email list from your Gmail search results.
