Let’s dive in.

Features to Look For in Cold Email Software

Schedule Campaigns and Automatically Follow Up

This is a cold email tool’s main function. While most cold emailing software has the ability to do this, the degree to which you can customize your campaigns and schedules varies between them.

The best cold emailing tools have functionality including:

  • Makes it easy to add and remove prospects from campaigns

  • Lets you schedule follow-up emails to send if someone doesn’t respond

  • Automates multichannel outreach steps like LinkedIn messages, cold calls, and SMS

  • Delivers advanced insights to help you get better results over time

  • Sends emails on a predefined schedule or time-zone based sending

  • Helps improve your email deliverability to ensure your emails land in the primary inbox

When choosing your cold email outreach tool, make sure that it has at least some of these features.

See the top reasons why people choose QuickMail.

Easy and Powerful Personalization

Cold email marketing won’t work if you don’t show your prospects that you understand their goals and motivations. You’ll need to personalize every email. Most cold email tools, including QuickMail, will let you use attributes to add snippets of personalization to emails.

You’ll be able to insert unique personalization for every lead like their name, company, custom intro lines and more. Take it a step further with custom links and suggested meeting days.

That way you can easily build a basic cold outreach template but insert unique, dynamic personalization so every email you send is custom to the recipient.

Reply Handling and Productivity Tools

All cold email tools allow you to send emails. However, sending your first email is just the first step. Ideally, your platform will include features to help you manage your pipeline of replies and continue the conversation.

For example, QuickMail logs all of your replies and tasks under the Opportunities tab.

Here, your team can easily track responses, and share notes and conversations.

This ensures that everyone on your team knows which prospects have replied and that no lead ever gets accidentally ignored.

Bring Your Whole Team and Collaborate

If you’re part of a fast-growing team, you’ll need collaboration features that enable multiple team members to work on your campaigns.

For example, you can have one team member working on your prospect list import. Another writing your cold email campaign copy. Another setting up your inboxes.

The result will be that everyone has focus, and you can send more high-quality outreach campaigns more quickly.

Look for features like a shared dashboard for your whole team’s campaigns, inbox rotation to change who emails are sent by, and analytics that let you see granular details on individual and overall performance.

If you're an agency, you'll also need features such as an agency dashboard to manage your client accounts, webhooks to automate processes, and an audit log to keep track of who does what.

QuickMail was the first cold email platform to offer inbox rotation. This lets you easily add and remove new inboxes from existing campaigns. It makes it simple to dial up your send volume without compromising your deliverability.

These are quality-of-life features that aren't common, but worth having if you’re planning on using cold email for lead generation.

Free Email Warm-Up & Best Deliverability

Good deliverability is paramount for the success of your cold email outreach, especially when done at scale. Look for email outreach tools that have deliverability features to help you keep your emails out of spam filters and maintain a healthy sender score in the long run.

For example, QuickMail users get free access to MailFlow. The native integration pushes warmer scores in real time for easy oversight.

QuickMail also offers features to boost deliverability: inbox rotation, minimum sending delays, enable/disable tracking, deliverability testing, and more.

QuickMail also offers free blacklist monitoring so you always stay on top of where your emails are landing.

Ready to send more volume? Just add an inbox (or five) to your existing campaign and QuickMail will start sending the same outreach campaign from multiple inboxes.

Using inbox rotation helps spread the send volume across multiple inboxes to keep send volume low.

Share reply handling among your team and view the entire conversation thread across different channels.

Answer from any inbox in your account and track deals won.

QuickMail’s AI features handle most of the admin workload for you: categorizing responses, handling unsubscribe requests, launching sub-campaigns, and more.

Free Email Warmup Integration

The first yet often overlooked step of email marketing is ensuring your emails reach people.

If your emails aren’t being delivered, nothing else matters.

QuickMail’s cold email software was built with deliverability in mind. With its native integration with MailFlow, a free email warm-up tool that has built-in deliverability tools, it ensures that your emails land in the primary inbox.

The integration is safe and Google-compliant. That means your campaign emails can still be sent from the Gmail API for best deliverability.

You’ll land in more people’s inboxes, and more people will reply as a result.

On top of that, QuickMail also generates a real-time auto-warmer score for each inbox to keep a tab on deliverability. Free SPF, DKIM, and domain blacklist monitoring ensure your emails aren’t breached and protect your domain and sender reputation.

A/Z Testing and Advanced Analytics

QuickMail is the only tool on the market with send-day attribution and advanced analytics to help you get more replies. This gives you better insight to monitor deliverability and campaign optimizations.


Focus on essential metrics like positive reply rates without getting sucked into vanity metrics or bot-inflated open rates.

QuickMail also provides context behind each data point, allowing you to take the right steps to optimize it. For example, it shows why people unsubscribe to optimize your list, messages, and contacts.

With un-capped A/B testing and the most advanced stats on the market - you can make smart campaign decisions that help you get better results in less time.


Whether you scale by inboxes, email sends, or seats - QuickMail is the best deal in outbound.

One perk with QuickMail is that team members are free. Every plan comes with a generous amount of senders, volume limits, and inbox rotation is included with every plan.

Paid plans start as low as $49/month for 30,000 monthly emails.

QuickMail provides a free 14-day trial that allows you to explore every feature of the tool.

When you sign up for the Auto-Warmer, you join a network of real inboxes exchanging emails and replying to each other. 

This mimics real email engagement, like the one someone would naturally have with their colleagues. This prevents email service providers like Google or Outlook from suspecting any unusual behavior and increases your deliverability.

The Auto-Warmer opens your emails, replies to them, marks them as "not spam", auto-archives them, and monitors your deliverability at all times.

The best part? It's completely free for QuickMail users and has a native integration to a powerful cold email platform, QuickMail. Try it yourself.

5 Bonus Tools to Improve Your Cold Email Campaigns

20. Find Emails with Clearbit Connect

It's a tool that finds emails and enriches your prospect profiles

Before you think of sending an email, you’ll need someone’s contact details. Tools like Clearbit Connect help you find the email addresses for people you want to reach out to.

As well as helping with email details, it’ll also help you find their social profiles (so you can connect with them) and other relevant details about their company, industry, job, and tools they use at work.

If you need help finding email addresses, it’s a great tool.

21. Verify Emails with NeverBounce

Verify your emails are valid and reduce your bounce rate with a tool like NeverBounce

High bounce rates are a bad sign. If your cold emails aren’t landing in your prospects’ inboxes, email service providers will see that you’re not using email in a natural way. You’re more likely to end up in the spam folder and you’ll see poor results from any email campaign you send.

To avoid unnecessary bounces, use NeverBounce to verify your email list.

Simply upload your contact list and NeverBounce will tell you if they’re valid or not, in under 10 minutes. Email verification is a simple but essential part of any successful outreach plan.

You can also verify your email list directly in QuickMail’s cold email software, thanks to our integration with email verification software like NeverBounce.

22. Send Personalized Videos with Loom

Record short videos that you can embed into your email marketing outreach

If you want to stand out in your prospects’ inbox, try using Loom to record a short video pitch instead of writing it out.

This is a great tactic to help show that you’ve done your research, have clear value to offer, and prove that you’re not just emailing 500 people with the same boring template, but are willing to put genuine effort into your outreach.

Loom links show up as a video preview in Gmail, so it’s a great way to make your cold email outreach stand out.

23. Automate Busywork with Zapier

Save time every day by automating repetitive tasks and connecting apps

Zapier lets you connect your cold email software to thousands of other tools and automate boring tasks.

  • Create a new deal in your CRM when someone replies

You’ll save hours every week, and don’t need to know any coding to use Zapier. It’s a great way to ensure your cold email marketing campaigns run smoothly.

However, it’s also important to remember that if you’re just starting out with cold email, don’t over-optimize things too early. Figure out what works, then start building your automations to suit your proven workflow.

4. What’s the Best Platform to Send Cold Emails From?

In truth, there’s no single best cold email outreach platform. The right one will depend on your needs and team setup.

We’ve found that for agencies and teams needing multiple seats and powerful cold email tools, QuickMail is a great option.

If you’re looking for something more lightweight, you might consider a tool that works as an extension, like Gmass or Streak.

5. What is the Benefit of Using a Cold Email Platform?

Cold email software lets you automate your outreach process.

Without software to help you, it would be time-consuming and require lots of manual steps to send personalized emails at scale.

Cold email software means you can run high-volume campaigns without worrying about deliverability, personalization, or forgetting to follow-up.

The only reason you shouldn’t use cold email software is if you don’t yet know who your ideal customer is or their pain points. In that situation, you should be reaching out to people one-by-one to start genuine exploratory conversations to see how you can help.

6. Is Cold Email Legal?

Yes, cold email is legal in most places.

Make sure to stick to the terms and conditions set out by your cold email outreach tool, and always review the laws in your country or region. For example, if you’re emailing prospective clients in the EU, you’ll need to abide by the GDPR. In the US, you’ll need to abide by the CAN-SPAM Act. If you’re in California, you’ll need to consider the CCPA.

As long as you have a good reason to email your prospects, create custom email templates for each person you reach out to, and don’t spam people, you won’t have much to worry about.

  • Verify your emails before sending to reduce your bounce rate

  • Use a cold email domain that’s separate from your main company inbox (QuickMail supports this)

  • Integrate social proof into your email templates to increase trust

  • Use an email warm up tool like the MailFlow to ensure your emails land in the primary inbox

Following these best practices means no matter what cold email outreach software you’re using, you’ll see great results.
