From AI-based personalization, predictive analytics for individualized send-time, and automated follow-ups, your cold email campaign doesn’t have to be a guessing game.

Snov.io is a popular cold email software that can help you automatize your email outreach campaigns. Where Snov.io really shines is its email validation capabilities. It can find emails from Linked In and websites. Then it will accurately track the email sequence to ensure optimal email deliverability.

Simply set up your email sequence and attach your prospect list.

Snov.io Pros and Cons:

  • Snov.io with find all the emails on your contact list. It will find multiple addresses per person, so you can choose to email all of them (which may lower your deliverability rates), or you can just send them to their more recent email.

Mailshake has been shaking up (pun intended) the cold email marketing software industry for quite some time now. They provide all the offerings of their competitors. You can create custom email templates, personalized cold emails, and send automated follow-ups, just as you would expect.

How Mailshake segments itself from the rest of the market is its multi-channel cold outreach approach: you can email, call, social media. It’s truly an omnichannel approach.

Mailshake’s Features

3. Instantly

Instantly is another cold email software that promises to provide you with a reliable email outreach system. It sends personalized emails, but with the help of artificial intelligence, they promise to increase your deliverability results for all of your sales and marketing campaigns.

They’re one of the few cold email tools that focus on minimizing your hard work turning into spam emails. As far as their dashboard and email sequencing, it’s pretty simplified and does everything you would expect.

Features of Instantly:

  • Email tracking is a breeze and easily seen through their analytics dashboard.
  • You can connect your email list easily through Google Sheets, CSV, or manually upload.
  • As they focus on improved deliverability, they have an unlimited warm-up option so that you never miss an email to spam. They’re the only platform I found with the unlimed option (typically, it’s limited to a few inboxes or is an additional add-on cost).
  • You have to pay a higher price to get the warm-up advanced technology.


Instantly is an affordable email software that provides you with high levels of deliverability. It missed out on some of the other bells and whistles when it comes to customizing send-times but gets your emails to the inbox.

4. Reply.io

Reply.io is a powerful automated outreach tool designed for outbound cold email campaigns. It helps you create highly personalized emails, automate follow-ups, and track responses using AI technology so that you can find the best prospects and convert them into customers faster.

What makes Reply.io unique from the rest of its competitors is that it includes an AI email assistant to help you construct your outreach efforts. Think of this like an email AI writer.

Reply.io Features:

  • Connects with your Gmail, Outlook, Exchange, and many other email service providers.
  • They have an AI email assistant that’s backed by GPT3 technology to help you write the most compelling outreaches.

  • You can schedule the day of the week and time for each follow-up to maximize your open rates.

If you don’t want email warm-up, it’s more affordable.


Overall, Reply.io performs all the functions you need in cold emailing software in one user-friendly dashboard.

5. Lemlist

Lemlist is another cold email software that does just that- it focuses on sending cold emails. It has the essential tools you need to get started, such as a warm-up period, automation of your entire email campaign, and affordable pricing.

So at this point, you may be wondering how they can stand out against the rest. I would say it’s their templates. They have fantastic email templates to really engage your leads and increase click-through rates.

Lemlist Good & Bad:

  • Gives you all the personalization and automation you could need from email software.
  • Lemlist has excellent customer support to walk you through the platform.
  • They integrate with all the major CRMs.
  • I love the scheduling option that’s customizable. You can choose to “send a new lead every 18 minutes”.
  • You have to purchase the warm-up email “Lemwarm” separately.


Their pricing is pretty industry-standard.


Lemlist is a great cold email software that gives you everything you need, plus great deliverability results. You do have to pay for the Lemwarm option separately.

6. Woodpecker

Well, it’s clear what Woodpecker does base on their title page alone. They claim themselves to be the ultimate cold email marketing software, and they have an entire page dedicated to this outlet alone.

Here are Some Features of Woodpecker:

  • They offer a “Cold Email Camp” to help you optimize your drip campaigns.
  • It integrates seamlessly with many other tools like Hubspot, Zapier and Hunter (will discuss this later).
  • Has everything else you would need from an email outreach software, such as personalizations, sending automated follow-ups, and A/B testing.
  • You can connect Hunter or Uplead to easily find prospects and connect them to Woodpecker. I thought this was a really nice touch.
  • There’s also a warm-up recovery option to help email addresses that have had delivery problems in the past.


Pricing varies based on how many emails you will be sent per month, as well as more for add-ons like A/B testing.


Compared to the competitors, I really love Woodpeckers’ capabilities to connect with lead-generating tools and the flexibility of their pricing. This is great for small companies that only want to pay for what they use.

7. Seventh Sense

Seventh Sense is a very new and unique platform that has been designed to integrate into Hubspot or Marketo. Most cold email tools work by you scheduling the day of the week, times, and time zones that you wish to send your outreach to.

What they don’t do is optimize each email to the user. While one person may open their emails on Tuesday afternoons, another may prefer Wednesday mornings.

This is where Seventh Sense comes in. Its cold email software optimizes the send times unique to each individual – an amazing demonstration of the artificial intelligence upgrades that will be introduced into business processes.

Here are the Pros and Cons of Seventh Sense:

  • Optimizes the send-time to each user to increase your open rates.
  • Integrates with Hubspot and Marketo.
  • You need to have the business version of Hubspot (small teams won’t work per their support). No way to integrate with other email platforms, so this is limited to larger companies.


Depends on if you’re integrating with Hubspot or Marketo. For whatever reason, the costs are much higher with Marketo than with Hubspot. It’s $450 per month with Marketo, but only $80 per month with Hubspot.


If you utilize Hubspot or Marketo as your CRM and cold email outreach platform, then Seventh Sense just makes sense. It’s the only platform to optimize individual user send-time to increase open rates.

8. GMass

Are you a small business just getting started with your AI email campaign? Maybe you don’t have a massive budget for a large emailing platform. Or perhaps you only need to send a few dozen emails a day, so it’s simply just not needed.

That’s where GMass can come in. It’s a Chrome extension that you set up with your Gmail account to send mass amounts of cold emails per day. Simply connect a spreadsheet (like Google Sheets) to the account, and it will automatically send emails from the list based on the parameters you set.

Features of GMass:

  • It’s relatively easy to use. Simply set up your spreadsheet with the parameters you want in your emails, like email address, name, or personalization. Then set up the GMass to send the email, and it will do it automatically!
  • You can set up an email warm-up feature to prevent emails from going to spam.
  • Set up customizable follow-ups automatically. This is a huge time-saver.
  • Staggers the emails, so you can change them to be sent every five minutes, so it’s not flagged.
  • You’re limited by how many emails you can send per day with Gmail. Also, keep in mind many may end up in the Spam box and not make it to their inbox.


You can start using their platform for free and then upgrade for an affordable price.


Overall, if you’re looking for a cheap alternative to email software, GMass is fantastic for a growing business. It saves a ton of time on auto-followup, and you can customize everything.

9. MixMax

MixMax is another popular platform for Gmail. It works a bit differently in that it has a nice dashboard to work from, but you can also do everything within your Gmail inbox. Within MixMax, you can click on each email recipient and add personalizations directly.

Some Things I Like About MixMax:

  • It gives you all the tools you need to deliver customization for authentic personalized cold email campaigns.
  • Attach MixMax to Salesforce if that’s your major sales platform. It also integrates with Zoom, Slack, and Google Calendar to help with your workflow.
  • They have “round robin” meeting scheduling to distribute the bookings across your sales team evenly.
  • It’s a bit pricier to get everything you need compared to the competitor


There are tons of option to choose from depending on your needs.


If you’re looking for a Google Chrome extension to implement with your Salesforce, then Mixmax is a great tool for this.

10. Hunter.io

Let’s say you’ve already established the cold email marketing software your company will use. But how do you find prospective clients to send cold emails and make your cold calls to?

That’s where a lead generation tool is a must, and Hunter.io is one of the most popular options on the market. It’s so easy to use, and you can get a lot of information for free.

Simply enter the website you’re looking to find a person from and find their email address.

Here’s what I love about Hunter.io:

  • You can find a lot of verified emails from the platform. Even if you don’t find the person you’re looking for, you can still relatively guess their email based on the format (first name only, last name, etc.).
  • You can still get a ton of information without subscribing to the platform.
  • Their dashboard is straightforward to use.
  • Sometimes, you won’t find the contact information you’re looking for.


You can use their platform for free. But if you’re building a list of thousands, you’ll need to upgrade.


If you’re looking to find some contact information, Hunter.io is a great place to start.

11. UpLead

What if you’re a company that is looking for more B2B prospects? Then UpLead is a great place to get a list of members in your target audience for your cold email outreach.

It essentially is one extensive database that can give you contact information for your targeted audience with reportedly high accuracy.

  • Instead of hiring people to manually collect cold emailing prospects, this platform does it for you in minutes. You can then take that list and integrate it with your cold outreach software.
  • If their contact information is incorrect, they’ll refund you the credit for the wrong information.


It can be a bit pricy.


If you’re a business that needs a list of leads without doing the legwork, UpLead is a great option. The accuracy of the contact information and customer service are unbeatable.

12. Warmer.AI

So now we’re getting to the point in your sales process where you’ve chosen a cold email platform, and maybe you’ve linked it with a lead generator like UpLead. The next question is, how can you take your personalization to the next level?

With software like Warmer.ai, you can actually add your lists’ LinkedIn contact information, and it will automatically check their profile to add in tidbits of customization.

So instead of the same old customization like “Hey {First Name}, This Offer Would Be Perfect For You!”, it could say something like “Hey {First Name}, I saw that you {personal note from Linked In} and I’m so impressed!”

I’ve Trialed the Software, and Here’s My Take:

  • It really takes personalization to the next level. It will find an article they posted or information from their bio and include that in the email to make you think only a real human could have found that.
  • Unfortunately, sometimes these customizations can be a bit vague, especially if they don’t utilize their LinkedIn accounts often.



While I think there is still a ton of room for improvement on the personalizations, I was amazed by how deep a level this AI software takes customizations. I’m sure this will be standard in a year or two.

13. Lyne.AI

Similar to what Warmer.ai offers, Lyne will also customize your email campaigns using public social profile information. Where Lyne differs is that it also offers a way to find new contact information with its chrome extensions.

For Cold Calling and Emailing, Here’s How I Think Lyne.ai Can Help:

  • Find contact information quickly with their extension
  • Create customized lines from their LinkedIn accounts and give you the most personalized cold email sequences you could get without manually crafting them.


You pay per credit, at I believe $0.05 per line.


If you’re looking for the most cutting-edge technology to add to your email marketing arsenal, Lyne.ai would be it.

What Is A Cold Email Outreach Tool?

A cold email outreach tool is a powerful software that helps you to reach out to potential customers with whom you don’t previously have a relationship. It allows users to send personalized emails, automate follow-ups, and track responses using AI technology in order to find the best prospects and convert them into customers quickly.

With an effective cold email outreach tool, businesses can increase their chances of success when reaching out to new leads or generating more sales.

There are also a ton of other AI marketing tools to help you increase conversions, such as:

What Are Factors To Look For When Choosing The Best Cold Email Software?

  • Ease of Use: You want software that is easy to set up and use so that you can start sending emails as quickly as possible. I prefer a platform that lets you do everything within one dashboard so you’re not constantly bouncing back and forth.
  • Cost: There are a variety of cold email software options available, ranging from free to subscription-based. Depending on the size of your company, be sure to pay only for what you need, as they can become quite costly.
  • Deliverability: The delivery rate is the percentage of emails that are successfully delivered to the recipient’s inbox. When selecting the best cold email software, you will want to choose one that will make it into your prospect’s inbox, not their spam folder.
  • Open Rate: The open rate is the percentage of recipients who open an email once it has been delivered to their inbox. A high open rate indicates that recipients are interested in the content of your emails (ahem, work on those subject lines!). When selecting a cold email software, you will want to choose one with a high open rate so that your emails are more likely to be read by recipients.
  • Click-Through Rate: The click-through rate (CTR) is the percentage of recipients who click on at least one link in an email once it has been delivered to their inbox. This matters because the goal isn’t for them to just open an email. The goal is to sign up for your course, purchase a product, and increase your sales. A high CTR indicates that recipients are interested in the content of your emails and are more likely to take action on your call-to-action (CTA).
  • Customizable Send Times: Traditional cold email outreach tools simply let you choose the day of the week and time you would like to send your email. But what about the timezone? Can it customize per individual user? Can it stagger the emails? These are things to look at.
  • Contact Hunting: Maybe you find a platform that can send bulk emails and drip campaigns for your company. How do you find the list of prospects? Does it integrate with a list builder? These are things to look for.
  • Reporting and Analytics: Without metrics, we can’t determine if our actions are successful or not. When selecting a cold email software, you will want to choose one with robust reporting and analytics features in easy-to-read detailed reports so that you can track your progress and make necessary changes to improve your results.
  • Education: The only way to get the most bang from your cold outreach is to use the tool to its fullest. You’ll want to see what type of onboarding or education features are included.
