10 Best Mailsuite Alternatives in 2026 (Free & Paid)  Tested & Ranked

So you’re done with Mailsuite. Maybe it’s the “Sent with Mailsuite” signature on every free email. Maybe it’s the daily digest instead of real-time alerts. Or maybe you just found out it doesn’t work on Outlook or your phone.

You’re not alone. Thousands of users search for Mailsuite alternatives every month  and the options have never been better.

We tested 10 tools head-to-head so you don’t have to. No fluff, no self-promotion. Just honest comparisons to help you find your perfect email tracking tool.

Why People Ditch Mailsuite

Before we dive in, let’s get honest about Mailsuite’s real problems. Because knowing why you’re switching helps you pick the right replacement.

The branding issue is real. Every email you send on Mailsuite’s free plan carries a visible “Sent with Mailsuite · Unsubscribe” footer. Your prospects can see it. For professional outreach, that looks cheap.

Daily digests kill your follow-up timing. Mailsuite’s free plan sends you a morning summary not an instant alert. If someone opens your email at 2 PM Tuesday, you find out Wednesday morning. That’s 17 hours of missed opportunity.

No mobile app. At all. Every email you send from your phone goes completely untracked. This is Mailsuite’s most-complained-about limitation on G2 reviews.

Outlook users are left out. Mailsuite is Gmail-only. If your team uses Microsoft 365 or Zoho Mail, you’re simply not supported.

The 10 Best Mailsuite Alternatives  Full Breakdown

1. Streak | Best Free Email Tracker for Gmail

Streak is the strongest free replacement for Mailsuite. Period.

Its free plan gives you unlimited email open tracking with zero branding on your outgoing emails. You also get a built-in Gmail CRM, mail merge, and a mobile app  all without spending a cent.

That’s the core problem with Mailsuite’s free tier solved in one tool.

Best for: Freelancers, consultants, and solo sales reps who want clean unlimited email tracking for Gmail without paying.

Key features:

• Unlimited tracking, no monthly cap on free plan
• No signature branding on any plan
• Built-in Gmail CRM pipeline
• Mail merge (50 recipients/day on free)
• iOS and Android app

Pricing: Free forever. Paid plans from $15/user/month.

One limitation: Streak is Gmail-only. No Outlook support.

2. MailTracker | Best for Real-Time Email Open Notifications

MailTracker does one thing brilliantly: it tells you the second your email is opened.

Not tomorrow morning. Right now. You get an instant Gmail notification the moment your prospect opens your message  and again every single time they reopen it.

That reopen signal is powerful. One open might be a quick glance. Three reopens over 48 hours? That person is seriously considering you. Mailsuite’s daily digest erases this intelligence completely.

Best for: Professionals sending critical individual emails  proposals, pitches, and follow-ups  who need real-time email tracking without any friction.

Key features:

• Instant open alerts  no daily summaries
• Reopen tracking per email
• No branding on any plan
• Link click tracking
• Lives entirely inside Gmail

Pricing: Free  20 emails/month. Paid from $29/month (unlimited).

One limitation: 20 emails/month on free is tight for high-volume senders.

3. GMass | Best for Gmail Mail Merge and Mass Outreach

If you need to send bulk personalized emails from Gmail, GMass is in a different league from Mailsuite entirely.

GMass runs mail merge campaigns directly inside your Gmail inbox  pulling contacts from Google Sheets, personalizing each email, and tracking every open and click per recipient. It also sends automated follow-up sequences based on who opened (or didn’t).

Mailsuite has none of this. It’s a tracker. GMass is a full cold email outreach platform for Gmail.

Best for: Sales reps, marketers, and recruiters doing high-volume Gmail outreach with automation.

Key features:

• Mass email campaigns directly from Gmail
• Per-recipient open and click tracking
• Automated follow-up sequences
• Google Sheets contact import
• A/B testing capability

Pricing: Free (limited). Paid from $12/month.

4. Mixmax | Best Gmail Sales Automation Tool for Teams

Mixmax turns Gmail into a complete sales engagement platform.

Where Mailsuite shows you who opened your email, Mixmax lets you build multi-step email sequences, embed one-click calendar booking inside emails, and sync everything directly to HubSpot or Salesforce. It’s a serious upgrade for any sales team.

Best for: Sales reps and recruiters who need email sequences, templates, and CRM integration  not just tracking.

Key features:

• Real-time open and click tracking
• Automated multi-step sequences
• One-click calendar scheduling in emails
• Salesforce and HubSpot native integration
• Email templates with merge tags

Pricing: Free (basic). Paid from $29/month.

5. Yesware | Best Mailsuite Alternative for Outlook Users

Here’s the truth: if you use Outlook, most tools on this list don’t help you. Yesware does.

It works natively in both Gmail and Outlook, has a mobile app for iOS and Android, and integrates directly with Salesforce. It’s the go-to option for enterprise sales teams on Microsoft 365 who want Mailsuite-style tracking without the Gmail dependency.

Best for: Outlook users, Salesforce-heavy sales teams, and anyone on Microsoft 365.

Key features:

• Native Gmail and Outlook integration
• Real-time open, click, and attachment tracking
• Template performance analytics
• Mobile app (iOS + Android)
• Salesforce bi-directional sync

Pricing: Free  10 emails/month. Paid from $19/user/month.

6. Boomerang | Best Budget Option with Email Scheduling

Boomerang is the cheapest paid option on this entire list at $4.98/month less than half the price of Mailsuite’s paid plan.

It works on both Gmail and Outlook, has a mobile app, and is the best pick when scheduling emails across time zones matters as much as tracking opens. Write an email at midnight, schedule it to land at 9 AM in New York.

Best for: Individuals and remote professionals who need both email scheduling and basic tracking.

Key features:

• Send later across time zones
• Open tracking with email notifications
• Follow-up reminders if no reply received
• Works on Gmail and Outlook
• Mobile app available

Pricing: Free 10 tracked emails/month. Paid from $4.98/month.

One note: Tracking requires manual activation before each send. Forget to click “Track” and that email goes untracked  no recovery.

7. Right Inbox | Best Affordable Gmail Tracker for Individuals

Right Inbox is a clean, lightweight Gmail extension that adds tracking, scheduling, and follow-up reminders. It’s highly rated on the Chrome Web Store and simpler to use than most tools here.

At $7.95/month, it’s more affordable than Mailsuite’s paid plan and more polished for individual daily use.

Best for: Individual professionals who want a clean Gmail email tracker without team features or complexity.

Pricing: No free plan (7-day trial). Personal plan $7.95/month.

8. Saleshandy | Best for Cold Email Sequences at Scale

Saleshandy is what you use when you’ve outgrown simple tracking and need a full cold email automation platform.

It handles multi-step sequences, email deliverability, inbox rotation, and supports both Gmail and Outlook. If you’re an SDR or agency running campaigns at volume, this is your tool.

Best for: SDRs, growth marketers, and cold email agencies scaling outreach campaigns.

Key features:

• Unlimited multi-step email sequences
• Inbox rotation to protect deliverability
• Built-in email verification
• Gmail and Outlook support
• Spintax for email variation

Pricing: Free  200 tracked emails/month. Paid from $25/month.

9. Snov.io | Best When You Need to Find Emails Before Tracking Them

Snov.io solves a different problem. It’s not just a tracker  it’s a full outbound prospecting platform that finds email addresses, verifies them, and then tracks your outreach.

If you’re doing cold prospecting from scratch, this combination is more efficient than using separate tools.

Best for: BDRs and SDRs who need to find, verify, and track email addresses in one workflow.

Pricing: Free  50 credits/month. Paid from $39/month.

10. HubSpot Sales Hub | Best for Teams Already on HubSpot CRM

If your team already uses HubSpot, you don’t need a separate tracking tool. HubSpot Sales Hub includes email tracking, sequences, and templates  and every open and click is automatically logged to your contact record.

The free plan covers 5 users, works on Gmail and Outlook, and has a mobile app. For HubSpot teams, this is the cleanest solution with zero extra setup.

Best for: Sales teams running HubSpot CRM who want tracking built into their pipeline automatically.

Pricing: Free for up to 5 users. Paid from $20/user/month.

Bonus: Need Cheap Google Workspace Mailboxes for Cold Email?

Here’s something none of the other comparison articles mention.

Most email tracking tools require you to already have Google Workspace set up  proper SPF, DKIM, and DMARC records, clean IP addresses, and warmed inboxes. Without that foundation, even the best tracker won’t save you from the spam folder.

If you’re setting up Google Workspace for cold email and want to keep costs low, Leads Monky is a certified Google Workspace reseller offering mailboxes from just $2.50/user/month  that’s 50–60% cheaper than buying directly from Google.

They’re trusted by 151+ companies and handle the full technical setup for you: DKIM configuration, DMARC setup, SPF records, spam protection, and email warmup all included at no extra charge.

Here’s how their pricing breaks down:

Plan	Who It’s For	Price
Fresh Setup (15–200 inboxes)	New cold email infrastructure	$2.99/user/month
Volume Discount (200+ inboxes)	Agencies scaling outreach	$2.50/user/month
Transfers	Existing Workspace migrations	$4.50/user/month

Every plan includes full cold email infrastructure setup  SPF, DKIM, DMARC, US-based IPs, and warmup guidance. It integrates with Instantly, Smartlead, Mailshake, and all major cold email outreach tools.

So the full picture looks like this: get your Google Workspace mailboxes through Leads Monky at $2.50/month, then plug in whichever tracker above fits your workflow. That’s a complete, affordable cold email infrastructure without overpaying.
