12 Best Email Outbound Software for 2024 (Features, Pricing)

12 best email outbound software

Email outbound software helps you send outbound emails to prospects.

And unlike inbound emails you send to subscribers, outbound or cold emails are personalized emails you send to people you haven’t interacted with before but with whom you would like to connect.

However, since the recipient might not know you, you’ll have difficulty engaging them.

Don’t worry.

With the right email outbound tool, salespeople and marketing teams can send successful outreach campaigns effortlessly.

In this article, I’ll go over what features to look for in an excellent email outbound tool. Then, I’ll cover 12 top email outbound software offerings, including their key features, pricing, and customer ratings.

Let’s get started.

What to Look for When Choosing Your Email Outbound Software

Here are five must-have features in email outbound software:

  • Email Personalization: Since recipients usually ignore generic outbound emails, you’ll need the capability to send personalized emails at scale.
  • Email Reports: Without email performance reports, you won’t know which outbound emails are effective and which ones aren’t.
  • Automated Follow-Ups: You can’t manually follow up on each outbound email, so you’ll need the functionality to send automated emails as follow-ups.
  • Email Scheduling: Scheduling features help your email reach the right inbox at the right time for better open and reply rates.

Now that I’ve covered the essential features, let’s explore the top email outbound software available today.

12 Best Email Outbound Software to Boost Your Sales

Here are 12 email outbound software tools you can use to approach and convert leads:

1. GMass


GMass is a powerful email outbound and email marketing automation solution that works inside Gmail. Its advanced cold email outreach functionalities have made it a popular tool used by employees in powerhouses like Google and Twitter.

This cold email tool is also perfect for sales and marketing professionals, startup founders, and small business owners — essentially anyone who uses email.

GMass Key Features

Let’s explore five GMass features you can leverage in outbound email campaigns:

A. Automatic Email Personalization

Most outbound email recipients may not know who you are. Naturally, if you send them a generic email like some amateur sales rep, it’s almost guaranteed to be ignored.

What do you do instead?
Simple: you send them tailor-made emails.

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

With GMass, you can automatically personalize:

This way, you can quickly personalize your emails at scale for each recipient, increasing your chances of connecting with them.


B. Bulk Email Scheduling

GMass lets you specify a date/time for your outbound email campaign. When it’s time, the tool will automatically send your emails.

This way, you:

  • Don’t have to be online when the sales or marketing campaign goes out
  • Can approach prospects across time zones

The best part?
Your emails reach prospects when they’re likeliest to engage, boosting your email open rate.

Bulk email scheduling

C. Detailed Analytics Reports

When you send an outreach or marketing campaign with GMass, it automatically generates a Campaign Report in your inbox.

This analytics report gives a clear picture of the performance of your tracked emails, including:

  • Open rate
  • Reply rate
  • Bounces
  • Unsubscribes, and more

Campaign reports

D. Automated Email Follow-Ups

A single follow-up email can boost reply rates by 21%. Imagine what multiple follow-ups can do!
However, manually creating and sending follow-ups is tiring.

Fortunately, you can automate the process with the GMass cold email software and send follow-ups until you receive a reply.

You can also choose:

  • What triggers the follow-up sequence
  • How many follow-ups to send
  • The time interval between follow-ups, and more

Automated followups

E. Email List Builder

An email list lets you send an outbound campaign to a large number of people easily.

Here’s how you can build an email list:

  1. Place “lead magnets” on your website to collect email addresses.
  2. Create an email list from your current contacts.

The #2 approach is much quicker and helps create a more targeted email list.

To create an email list in GMass, all you have to do is perform a Gmail search with keywords related to your target audience, and GMass will automatically build the email list for you.

Email list builder

You can also easily connect an email list stored in Google Sheets, Excel, or a CSV file to GMass.

But that’s not all!

GMass supports various other advanced features to take your outbound email campaigns to the next level.

Other Powerful GMass Features

Here are some more useful GMass features:

  • AB Testing: Perform an AB test to identify which email variation has the best responses.
  • Mail Merge: Create a mail merge campaign by connecting your Google Sheets file to GMass. You can also convert your Excel or CSV file to Sheets and connect it to GMass.
  • Behavior-Based Campaigns: Send campaigns customized to how recipients responded to your previous emails.
