This guide breaks down:

• Core feature differences
• Deliverability tools
• LinkedIn support
• Sending infrastructure
• Pricing
• Who each tool is best for

Feature Comparison: SuperSend vs Instantly

SuperSend is built for high‑volume, multi‑domain outbound across email and LinkedIn, with deep deliverability intelligence and flexible team workflows.

Instantly is built for high‑volume cold email sending only, with a strong warm‑up network and simple UI — but no multichannel support and no LinkedIn.

Below is a full breakdown.

1. Multi-Domain Email Sending

• SuperSend supports many domains and inboxes inside one workspace, ideal for large‑scale outbound.
• Instantly also supports multi‑domain sending, though it is limited to email‑only outreach.

2. Inbox Rotation

• SuperSend uses a smart load‑balancing algorithm that distributes sends across inboxes and campaigns based on demand.
• Instantly rotates inboxes as well, though without multi‑channel routing logic.

3. Deliverability Intelligence

SuperSend provides:

• Inbox placement testing
• Live inbox vs spam scoring
• Domain and inbox health monitoring

Instantly focuses more on warm‑up volume than diagnostics and does not offer real‑time deliverability insights.

4. Multi-Identity LinkedIn Sending

• SuperSend supports multi‑identity LinkedIn sending for $69/profile per month.
• Instantly does not offer any LinkedIn automation.

5. Multi-Channel Sequences

• SuperSend supports unified sequences across email and LinkedIn.
• Instantly is email‑only by default. Instantly recently added an integration with Heyreach for multichannel outreach, but this requires users to purchase and manage a separate Heyreach account.

6. Google/Outlook Inbox Setup

• SuperSend can provision Google and Outlook inboxes directly.
• Instantly requires users to connect their own inboxes manually.

7. Dedicated Sending Infrastructure

• SuperSend offers optional private dedicated sending infrastructure for teams needing full isolation.
• Instantly relies entirely on your connected Google and Outlook inboxes, similar to SuperSend.

Choose SuperSend if:

Super Send Vs. Gmass: Which Is Better for Cold Outreach?

What do you prefer in cold outreach software—ease of use, loaded features, or not paying an arm and a leg for the chance to reach your leads?

When it comes to cost and usage, Gmass has won many battles against many of its competitors. B2B sales pros and entrepreneurs alike users love the mail merge and auto follow-up features and find them reliable.

But while Gmass is a great tool for sending and tracking email campaigns, it has some limitations that make it less than ideal for strong and comprehensive cold outreach strategies.

In this article, we’ll go over some of the limitations of Gmass as a cold outreach tool and how it compares to Super Send (an all-around cold outreach tool).

What Is Gmass?

Gmass makes cold emailing super-convenient—users can perform cold outreach directly within their Gmail inbox. All they need is to download an extension and start using Gmass from their Gmail inboxes!

source

Gmass helps you:

• Automate your email sequences by setting up automated replies
• Integrate Google Sheets to fetch leads’ data
• Personalize your emails
• Verify email accounts
• Warm up your email account
• Get instant access to insights about open rates, clicks, and replies via live reporting
• Segment leads into different groups

While Gmass works wonderfully for many businesses looking to acquire more leads, it’s still not the best cold outreach option!

Limitations of Gmass

• Gmass doesn’t have a dedicated user interface, which can be very old-school for some people.
• Gmass isn’t an all-in-one solution—you still need to rely on other tools to perform outreach for other platforms and increase your sending limit.
• For its price, it doesn’t offer many other cold outreach features like personalized images, Twitter Automation, and LinkedIn automation.

Super Send vs. Gmass

Super Send is an excellent alternative to Gmass as it offers many more features than Gmass. Bonus? It’s cost-effective to boot!

From list-building to automated follow-ups, you name it—Super Send assists its outreach experts with everything they’ll ever need to run successful outreach campaigns.

Super Send Focuses on Multi-Channel Campaigns

When it comes to engaging with leads, you can never be sure where they’re hanging out. They might not even open their email for days and still be hanging out on LinkedIn or Twitter. And you don’t want to miss out on the opportunity just because your tool doesn’t offer that flexibility.

Unlike Gmass, Super Send isn’t just about cold emails—it covers more ground by allowing multi-channel campaigning to target leads on multiple channels.

Besides cold emailing and sequence building, Super Send also allows you to reach out to your leads on social media like LinkedIn and Twitter.

Following and Cold DM-ing Prospects Is Easy!

The Twitter and LinkedIn automation feature allows you to reach out to your leads and automatically follow accounts.

Just add the automation features to your sequence and set up the DMs or the connection request notes for LinkedIn.

Super Send vs. Gmass: Cost

Gmass has 3 different pricing tiers starting from $19.95 per month, whereas Super Send’s cost starts at $30 per month.

Even though Gmass is cheaper, it doesn’t even offer crucial features, including sequencing and follow-ups, A/B testing, and integration. And if you want access to these features, you’ll need to upgrade to their premium plan, which costs 29.95 per month.

Super Send offers everything that Gmass’ premium plan offers and more at nearly the same price.

Clearly, Super Send is more cost-effective when comparing price vs. features!

Super Send’s Inbox Rotation

Gmass enhances Gmail’s sending limit and allows you to send up to 500 emails or 2000 emails per day, depending on whether you have a Google Workspace account or a simple Gmail account. While this works with some small businesses and solopreneurs, it can be a deal breaker for someone looking to scale their outreach efforts.

That’s where Super Send’s inbox rotation feature comes in handy!

You can send emails for a single campaign from multiple inboxes and not necessarily from the same domain. This way, you can increase the sending volume even when you’ve hit your email server’s sending limit and reach more leads at the same time.

Twitter List Building with Super Send

List building is a new addition to Super Send’s stack, allowing you to seamlessly build a list of leads from your Twitter account.

All you need to do is plug in a username, and Super Send will populate their follower list and add them to your list of leads.

Take Sequence-Building to the Next Level with Super Send

Hyper-targeted sequence-building is another excellent addition to Super Send’s set of features, making it one of the strongest and simplest cold outreach tools in the market today!

You can create laser-focused sequences (email, connection request, DM on either Twitter or LinkedIn, or replies to DMs or emails) with the next-level drag-and-drop functionality.

Simply create the skeleton for the entire outreach sequence in one go and edit as you go!

Moreover, you can also apply conditional statements (or triggers) to each step in your sequence.

On the other hand, Gmass offers very basic-level sequencing functions, which is only effective for those outreaching on a small scale.

Super Send Helps You Scale Your Outreach Efforts Holistically

Super Send wins the race when it comes to cost, features, and scalability. It’s a reliable cold outreach tool for B2B professionals looking for the perfect tool to get more leads without wasting time or money.

Whether you’re just starting to cold outreach or looking to scale your campaigns, Super Send is the best Gmass alternative with unrestricted plans and super-intuitive UI.

Super Send Vs. Mailshake: Which Cold Outreach Tool Is Best For You?

Cold outreach becomes a cakewalk when you have a reliable and efficient cold outreach tool supporting you! ‌
‌

All you need to do is feed it with some of your best leads (read: good-quality leads), and it will take care of the rest. ‌
‌

So today, we’re comparing two cold outreach tools—Super Send and Mailshake—to help you find the best solution at optimal cost. ‌
‌

Let’s dive in!

Super Send Vs. Mailshake: Feature Comparison

Ease of Use

Personally, I prefer tools that have a low-learning curve and are easy to grasp from the get-go. ‌
‌

While Mailshake makes it convenient to link your Gmail or G-suite account and send emails directly from your Gmail account, you’ll still need to use their interface for managing your campaigns. ‌
‌

Changing interfaces for different functions gets annoying when working with multiple campaigns. It also increases the onboarding time, as getting used to this setting takes more time. ‌
‌

‌

‌

‌
‌

Regardless, Mailshake’s UI is pretty intuitive—you can literally start using the platform without prior knowledge of how it works. ‌
‌

Super Send has a highly flexible UI. ‌
‌

Creating campaigns is as easy as dragging and dropping email sequences (nodes)—and the best part is it’s all manageable from one page. ‌
‌

You’ll be able to hyper-personalize your messaging to boost your conversion rates with:‌
‌

• Conditions
• Rules
• Triggers
• Segmentation‌
  ‌

‌

‌

Prospecting

Mailshake is quite adept at what it offers—sales engagement through cold email automation and LinkedIn automation. Its newest addition, “Prospect Finder,” helps search for prospects by their job role, company location, and other criteria. ‌
‌

While Prospect Finder is free with both pricing plans of Mailshake, you only get a limited number of credits you can use for prospecting. Beyond that limit, you’ll need to pay extra to use the service.‌
‌

Super Send, too, has introduced 2 new features to aid in prospecting to its arsenal:‌
‌

• Email finder
• Lead enrichment‌
  ‌

These features help you find new leads and qualify them before you even start your cold outreach, helping you make informed decisions about your leads. ‌
‌

Moreover, the list-building functionality by Super Send helps build a list of leads from Twitter.‌
‌

Simply plug in the username, and you’ll get the target’s followers populated in your list. ‌
‌

‌

‌

‌
‌

Multi-Channel Outreach

Mailshake helps you reach your leads via emails and LinkedIn profiles. You can make LinkedIn Automation a part of your sequences and connect with a lead through both channels. ‌
‌

Super Send is one step ahead in multi-channel outreach. It brings Twitter automation into the picture—just in case your leads are hanging there instead of LinkedIn and their inboxes. ‌
‌

The Twitter outreach feature allows you to automatically DM your leads and follow accounts—just add Twitter or LinkedIn prompts to your sequence, and you’re sorted!

Email Personalization

Both Mailshake and Super Send allow you to personalize specific elements of your emails through message variables and merge tags. ‌
‌

All you need to do is upload a CSV file of your leads; these tools will automatically pick data from it (considering it’s in the correct format). ‌
‌

With Mailshake, you can send bulk personalized emails to your leads and preview your outreach emails to see how they appear for each lead. You can make edits in the preview stage for every lead.‌
‌

‌

‌

‌
‌‌
‌

Super Send, on the other hand, offers the image personalization feature, which makes your emails more relatable, funny, or intriguing.

Inbox Rotation

Most email service providers and cold outreach tools restrict the number of emails you can send daily. You can get blacklisted if you surpass the sending limit, and it will only risk you landing in your recipients’ spam folders. ‌
‌

That’s where inbox rotation comes in! It connects multiple inboxes with multiple email addresses (or domains) to your cold outreach tool, allowing you to send emails from multiple addresses. ‌
‌

This way, you can continue your outreach journey without stopping. ‌
‌

Super Send has the inbox rotation feature, but Mailshake doesn’t, which can be a turn-off for those looking to scale their outreach efforts beyond the limits set by their tools.

Email Warmup

Both Mailshake and Super Send allow you to enable email warmup. ‌
‌

Mailshake has an external tool, Warmup Your Email, that does the job for you by sending emails from your account to their own email accounts. Their system automates replies from these email accounts, helping you warm up your email account for better deliverability. ‌
‌

Unfortunately, if you want to use this feature to avoid ending up on a blacklist, you’ll need to pay extra.‌
‌

However, with Super Send, you get this feature with the tool included in the price.  ‌
‌

Just enter the number of emails you wish to send out each day and the count by which you want to increase the frequency, so email service providers get the hint that you’re legit and you avoid landing in the Promotions tab (or the Spam folder). ‌
‌

‌

‌

Cost Vs. Features

Mailshake’s pricing plans start from $58 per month, suiting businesses of all sizes—solopreneurs and businesses with large teams. While you get a commendable number of features for the price, it is still costlier compared to Super Send’s list of features and plans. ‌
‌

Super Send’s pricing depends on the number of emails and campaigns you send and the number of team members and email senders you add every month. The basic plan starts at $30 per month, which is a steal, considering the abundance of features.

Final Verdict: Which Cold Outreach Tool Should You Choose?

Super Send ticks most checkboxes when factoring in different parameters of the two cold outreach tools. ‌
‌

While Mailshake is a reliable sales engagement platform for sales teams starting their outbound outreach process, Super Send wins the race and comes off as the better choice. ‌
‌

It’s cost-effective and offers multiple essential features for B2B sales professionals looking to start or scale their cold outreach journey.

‌

‌

Moreover, Super Send’s team keeps introducing new features to their stack, making it an all-powerful sales engagement platform!‌
