Cold email prospecting, aka cold emailing, is vital in expanding your B2B and B2C business. There is no doubt that cold email is a go-to channel for customer acquisition.

However, the outcome is solely based on your cold email best practices and the effectiveness of your chosen cold outreach tool.

By reading this article, you will be capable enough to choose the right outreach tool based on your requirements without spending much of your valuable time.

You will learn whether email warmup is a valid ethical way, the importance of custom domain, and mailbox switching.

Here’s the hawk-eye view of the comparison:

Before diving deep, get to know how I ranked these cold outreach software.

Instead of throwing a bunch of software lists, I extensively used all of these cold outreach software tools personally and have communicated with their customer service representatives for certain features and functional confirmations.

Table of Contents

Let’s start by clarifying the distinction between cold email outreach software and email marketing software.

Firstly, it is important to understand the fundamental difference between cold emails and marketing emails.

Cold emailing is specifically geared towards contacting a targeted group of leads who are not be familiar with your product or service, whereas email marketing encompasses broader strategies aimed at engaging with existing customers or a wider audience.

Now, let’s move on to the differences between cold email outreach software and email marketing software.

Even widely recognized email marketing software comes with specific terms and conditions and their nature may not align with the practices of cold emailing. These include:

  • requirement of client consent for sending emails

  • their SMTP servers can land cold emails in the promotion tab due to their newsletter-friendly standard

  • Lack of smart scheduling of emails

  • Some providers share email servers, so if one customer gets marked as spam due to their numerous mail requests, it affects others on the same server.

  • Hence, choose the tool wisely based on this knowledge.

    Ok, without further ado, let’s have a sneak peek of insights about the comparison tools.

    A Sneak Peek Before the Comprehensive Comparison

    Based on my research,

  • Almost 75% of cold outreach software listed here has an email warmup feature

  • 83% of cold outreach tools in this list have mailbox rotation features, which allow them to escape from the spam filter and increase the sender reputation score

  • Almost 99% of outreach tools have generative AI support for email creation including some of them having AI support for whole sequence creation

  • While all tools have the support for personalization, a few like GoZen Growth and Lemlist support advanced personalization using liquid formulas

  • All of the cold outreach software/ tool offers free trials, except Outreach.io. Among these, GoZen Growth, Apollo, and Snov.io offer lifetime free plans.

  • I know it is difficult to choose from one cold outreach software from this sneak peek since they all share more or less similar features.

    To get a deep understanding of functionalities tests that explore the pros and cons of every tool, you need to read the full article.

    Essential Features of Cold Outreach Software for Optimal Deliverability

    Cold outreach software must have the following essential features for optimal performance.

    Email Warmup

    Email deliverability is the primary concern in cold prospecting. We all know that high email deliverability is the first win in cold emailing.

    To increase the email deliverability of particular domains, vendors in the cold outreach niche came up with a feature called “email warmup”.

    Email warmup is an advanced feature powered by AI that takes over enrolled email accounts and initiates human-like conversations between them with smart scheduling.

    Sending emails gradually in a specific period from a new email account will help in building a positive reputation for that account. As a result, the account can send an increased amount of emails without landing in the spam folder.

    Though the email warmup has been giving a decent improvement in inbox deliverability, the feature might be disabled in the future as Google already asked one of the cold outreach software vendors to disable it lately.

    So just because email warmup gives a favorable outcome in the present, it doesn’t mean it is the only considerable factor.

    Sender Rotation

    Sender rotation can be a perfect alternative for email warmups. Since the warmup feature shows uncertainty in its existence in the long run, you can rely on sender rotation.

    Sender rotation is one of the essential features of cold outreach software, which allows you to seamlessly jump between multiple email accounts of the same domain to ensure better deliverability for your cold outreach campaign.

    Custom Domain Tracking

    The use of custom domain tracking is another ethical way to increase your cold email deliverability. Some of the vendors provide shared domains, which may affect your deliverability for someone’s malpractice.

    In addition, implementing custom domain tracking increases brand and professionalism and reduces the likelihood of phishing flags.

    If Google clamped down email warmup, the custom domain can be a reliable factor that can guarantee email deliverability.

    Implementation of Strong Authentication System

    When it comes to the email authentication systems (DKIM, DMARC, and SPF), it is in both hands of the sender and vendor.

    While DKIM is taken care of by your vendor and you are responsible for dictating the SPF and DMARC.

    Stating that, if a cold outreach vendor failed to sign your email due to a lack of technical issues, your email would end up being in spam.

    Multi-Channel Marketing

    Though your primary aim is to do cold emailing, having an additional channel to market is a bang for the buck.

    The other channel can be web and mobile push notifications and some vendors even combine LinkedIn outreach and cold calling along with cold emails.

    Powerful Integrations

    A powerful integration is a must for cold outreach software. Integration support for CRMs, and workflow software like Zapier and Pabbly is a great addition.

    The integration enables bi-directional data flow between the application that leads to real-time collaboration, enhanced user experience, efficient data processing, and reduced latency.

    Lead Database

    Lead database in my opinion is not a necessary feature that you could expect from a cold outreach vendor.

    The challenge with the standard lead database provided by any cold outreach software vendor is that it’s likely been heavily used by other customers of the same vendor.

    This can make it harder to stand out and build meaningful connections with potential customers.

    It can backfire and damage your reputation in some cases as those leads are getting continuous cold emails from multiple sellers.

    If the lead database provided by the vendor is updated frequently, you can give it a try. Otherwise, you can start your cold outreach campaign with your own set of lead lists.

    On the whole, choose the cold outreach software based on these factors. Do not only focus on the email warmup feature since its presence is uncertain.

    Apart from email warm-up, the other features mentioned above must be in a cold outreach tool for better email deliverability.

    Best Cold Outreach Tools/ Software

    GoZen Growth

    G2: 4.8/5
    Capterra: 4.7/5
    AppSumo: 4.8/5

    GoZen Growth is a comprehensive and the most affordable email marketing and cold outreach software (2-in-1) that guarantees the optimal deliverability of your cold emails.

    Why GoZen Growth is on the Top of the List?

    It is because it has all the essential features for your cold email campaigns. Apart from that, it is the only tool in the market that can be used for both cold emails and email marketing.

    Email Deliverability

    Growth has features including mailbox rotation, automated email warmup, smart drip campaigns, and advanced personalization to ensure optimal cold email deliverability.

    Sender rotation allows you to send cold emails from various email addresses of the same domain.

    It helps you to send cold email campaigns that don’t feel like generic email blasts, without getting into spam filters and not exceeding the daily limit of emails sent.

    The automated email warmup feature of Growth is an advanced and novel way of increasing your email sender reputation score.

    Leveraging the natural language processing (NLP) technology, Growth composes emails with human touch and randomly communicates across thousands of other real human email accounts in our warmup pool.

    This complete autonomous process of email warmup takes place in the backdrop, without interrupting your cold outreach campaigns.


    This complete process of meaningful conversations, along with thoughtful follow-ups, will significantly improve your sender reputation for the email account you’ve warmed up.

    Smart drip campaigns, an another advanced feature of Growth that is built for better cold outreach deliverability.

    Using the smart drip campaign, you can set your whole cold outreach on auto-pilot by pre-setting the email sending frequency, time, and limit per email account.

    The algorithm manages initial emails and follow-ups in a controlled manner, intelligently detecting replies and halting follow-up emails.

    Growth Smart Drip Campaigns

    By rotating sender email accounts and scheduling limited emails strategically, it mitigates the risks associated with email blasts and ensures a human-like sending pattern to improve inbox delivery rates.

    Personalization is another essential factor to connect with your leads and capture their attention. It is also another email deliverability factor that you should add to your campaigns. With Growth, you can go beyond simple first name personalization.

    By leveraging liquid formulas, you can effortlessly create custom emails for each prospect on a large scale. Now, you must have realized that generating dynamic emails at scale is a breeze with Growth.

    Growth liquid personalization

    Growth will soon get the update of the custom tracking domain which will also increase the credibility and email deliverability of the sending domains.


    Of course, every cold outreach tool comes with an automation feature. Apart from initial email sequences and follow-up automation, Growth has an automation workflow setter called Journey Builder.

    With Journey Builder, you can set up email sequences with time delays based on user actions.

    Growth journey builder

    Since Growth is powered by generative AI assistance, composing emails for your campaigns and warmup process can be done with a single click of a button.

    Multi-Channel Marketing

    Multi-channel marketing automation is another added advantage to attract more new customers.

    Having LinkedIn as a multi-channel approach has its disadvantage of platform restriction. LinkedIn has limitations on outreach, connections, and messaging.

    Violating these rules can lead to account restrictions or suspensions, affecting your marketing efforts.

    On the other hand, reaching out to your lead on both email and LinkedIn sometimes can be too intrusive.

    Hence, Growth offers a push notification channel, a responsive customer communication channel for better engagement.

    Using push notifications, you can reach your customers via your web as well as your lead or prospect’s Android devices.

    Growth push notifications

    Apart from push notifications, you can also use the sign-up forms feature either as a website embeds or pop-ups to collect lead information. This is one of the unique feature of Growth which all other competitors are lacking.


    Currently, Growth has Zapier, Pabbly, WooCommerce, and Shopify integrations.

    It also has native integration support for Optinly, an advanced drag-and-drop website popup builder.

    Growth has a promising roadmap for integration to make the cold outreach software more powerful with leading CRM and other email marketing tools.

    Here’s a sneak peek of Growth’s upcoming integrations:

    Klenty is a fully equipped sales engagement platform for your sales team. It allows you to find prospects, make sales engagements (email, cold call, & LinkedIn), and automate meeting schedules.

    Unlike other end-to-end sales engagement platforms, you need to pay separately for each of their solutions.

    Pros of Klenty

  • Personalize emails with video

  • Well-segmented pricing details

  • Good template library

  • Easy inclusion of “Unsubscribe” link, just like GoZen Growth

  • Multichannel engagement with emails, calls, LinkedIn, SMS, and WhatsApp

  • Cons of Klenty

  • Absence of automated email warmup

  • Based on pricing, it might not be a fit for small businesses and startups

  • I have experienced latencies at every click that I made inside the application

  • Since it is a complete sales engagement platform, I feel like they have given less importance to the user interface and functionalities of the cold email automation section

  • The response from their chat support was significantly delayed. Each question I asked was met with a prolonged wait, with the message status “seen”.

    If you plan to send bulk emails, ensure to add an opt-out option in the form of an Unsubscribe button. As per Google’s new standard, all bulk senders should include the opt-out option, failing to add this will lead to spam.


    GoZen Growth has all the important features for better cold email deliverability.

    Apart from this, GoZen Growth is the only tool in the market that can be used for both email marketing and cold outreach campaigns (2-in-1) since it is equipped with features for both. Cold Outreach Features of Growth: Automated email warmup, sender rotation, custom domain tracking, strong authentication management, smart sequences builder, and personalization.

    Email Marketing Features of Growth: Generative AI support, sign-up forms, push notification system, automation, and pro segmentation.


    Is email warm-up illegal?

    Email warm-up is not openly stated as illegal. However, Google clamped down the email warmup feature of one of the cold outreach software vendors since they overdid it. Hence, it is important to stay within the limit regarding email warmup. Cold outreach software like GoZen Growth smartly handles the warmup process with human-like conversations and limited communications per day, which mimics the human sending frequency.

    Also, Growth uses IMAP instead of Google API for email warmups. So, there is no risk of violating the API rules.

    What is the difference between cold outreach and cold emailing?

    While both cold outreach and cold emailing refer to the act of initiating contact with potential leads or prospects who have had no prior interaction with your business or brand, they have distinct differences.

    Cold outreach is a broader term that encompasses various methods of reaching out to potential leads, while cold emailing specifically refers to the strategy of initiating contact through email without prior permission or relationship with the recipient.

    The cold outreach includes various methods such as cold calling, cold emailing, social media outreach, direct mail, etc.

    The cold emailing is typically emails sent to introduce your offering, share information, or request a meeting or call with the recipient.

    How to avoid email going to spam?

    To stop emails from going to spam, you should use cold outreach software that has features, such as email warmup, sender rotation, smart sequences automation, personalization, and custom domain tracking.
