7 best GMass alternatives in 2026 (compared)

GMass is one of the best-known ways to send mail merge campaigns from Gmail. But it raised its prices (again) in January 2026, it only works inside Gmail and Chrome, the interface is clunky and automated follow-ups aren’t included in its entry plan. So whether you want to pay less, use Outlook, or move to a full cold email platform, it’s worth knowing your options.

In this guide, we compare 7 GMass alternatives on features, pricing, and the type of user each one fits best. We built Mailmeteor, which is on this list, so we’ll tell you where it’s the better pick — and where another tool will serve you better.

Why Look for a GMass Alternative?

GMass is a Chrome extension that turns Gmail into a mass email tool. You write your campaign in the Gmail compose window, connect a Google Sheet, and GMass sends a personalized copy to each recipient. It’s powerful, with A/B testing, triggered emails, and inbox rotation on its higher plans.

Here’s what GMass costs for individual users:

Team plans start at $175/month for 5 users.

That’s a solid feature set, but a few things push users to look elsewhere:

• The price keeps climbing: GMass increased its prices once more on January 1, 2026, and follow-up sequences now start at $39.95/month.
• Gmail and Chrome only: if you or your team use Outlook, GMass isn’t an option.
• Everything happens inside Gmail: there’s no standalone dashboard to manage campaigns outside your inbox.
• Email only: there are no LinkedIn or phone steps for multichannel outreach.

If one of those sounds familiar, here are the alternatives worth considering.

GMass Alternatives at a Glance

Here’s how the 7 alternatives compare ⤵️

1. Mailmeteor

Mailmeteor is the closest like-for-like replacement for GMass. Like GMass, it sends personalized emails from your own account using data from a spreadsheet. But it isn’t limited to Gmail and Chrome: you can send campaigns from Google Sheets, Gmail, Google Docs, Outlook, Excel, or the Mailmeteor Dashboard.

Mailmeteor is trusted by more than 7 million users, rated 4.9/5 across 10,000+ reviews on the Google Workspace Marketplace, and recommended by Google for Google Workspace.

Best for: freelancers, small businesses, and teams who want GMass-style mail merge at a lower price, in Gmail or Outlook.

Pricing: the free plan lets you send up to 50 emails per day, with no time limit and no credit card required. Paid plans start at $4.99/month. See all plans on our pricing page.

Pros of Mailmeteor

• Works beyond Gmail: send campaigns from Google Sheets, Gmail, Google Docs, Outlook, or Excel — or manage everything from the Dashboard.
• Cheaper than GMass: a free plan, and paid plans that start well below GMass’s entry price.
• Follow-ups and tracking: send automatic follow-ups and track opens, clicks, and replies in real time.
• Deliverability tools built in: BounceShield verifies addresses before you send, Autopilot spreads your sends over the day, and email warm-up builds the reputation of new or dormant addresses.
• Inbox rotation: on the Pro plan, spread a campaign across up to 10 senders.
• Easy to learn: you can set up your first campaign in a few minutes.

Cons of Mailmeteor

• Bound by your provider’s sending limits: each sender can’t exceed its own Outlook or Gmail daily limit.
• Not built for massive volume: inbox rotation is capped at 10 senders per campaign, so teams running dozens of mailboxes are better served by Instantly or Saleshandy.
• Email only: there are no LinkedIn steps or phone dialer. If you need multichannel sequences, look at lemlist or Mailshake.

2. YAMM (Yet Another Mail Merge)

YAMM is a Google Sheets add-on that sends personalized emails through Gmail. If GMass feels like more than you need, YAMM is the no-frills option: connect a sheet, pick a Gmail draft, and send.

Best for: occasional senders who want simple mail merge from Google Sheets.

Pricing: the free plan lets you email up to 20 recipients per day. Paid plans cost $25/year per user for Gmail accounts (400 recipients/day) and $50/year per user for Google Workspace accounts (1,500 recipients/day). See our guide to YAMM pricing.

Pros of YAMM

• Very simple: fewer settings than GMass, so it’s quick to learn.
• Low annual price: much cheaper than GMass for basic mail merge.
• Tracking included: opens, clicks, and bounces are reported back into your spreadsheet.

Cons of YAMM

• No automated sequences: YAMM focuses on one-off mail merges rather than multi-step follow-ups.
• Small free plan: 20 recipients per day is only enough for testing.
• Google only: like GMass, it doesn’t work with Outlook.

3. Instantly

Instantly is the alternative for GMass users who’ve outgrown sending from one Gmail account. Instead of working inside your inbox, it’s a dedicated cold email platform where you connect as many mailboxes as you need, warm them up, and rotate sends across them.

Best for: sales teams and agencies sending thousands of cold emails per day.

Pricing: Growth costs $47/month, Hypergrowth costs $97/month, and Light Speed costs $358/month. The lead database is billed separately. There’s no free plan, but you can start with a free trial.

Pros of Instantly

• Unlimited email accounts: spread your volume across as many inboxes as you want.
• Built-in warm-up: included on every plan.
• Unlimited team seats: pricing depends on volume, not on the number of users.

Cons of Instantly

• More setup: you’ll need separate domains and mailboxes to use it well.
• Extra costs: lead data and CRM features are billed on top of the sending plan.
• Overkill for mail merge: if you send newsletters or updates to people who know you, a Gmail-based tool is simpler.

4. Saleshandy

Saleshandy is a cold email platform built around value. Every plan includes unlimited sending accounts and email verification, and its entry price is close to GMass’s — with far more sending capacity.

Best for: small teams that want a full cold email platform for about the price of GMass.

Pricing: Outreach Starter costs $36/month for up to 2,000 active prospects and 6,000 emails per month. Outreach Pro costs $99/month. Read our guide to Saleshandy pricing to learn more.

Pros of Saleshandy

• Unlimited email accounts: connect as many sending accounts as you need on every plan.
• Email verification included: every plan comes with verification credits.
• Affordable on annual billing: the annual Starter plan costs less than GMass Standard.

Cons of Saleshandy

• Starter is single-user: team members and CRM integrations start on Outreach Pro.
• Separate platform: you’ll manage campaigns outside Gmail, which takes some getting used to.

5. lemlist

lemlist goes beyond email. It’s a sales engagement platform that combines cold email, LinkedIn steps, and calls, with advanced personalization like custom images and videos for each prospect.

Best for: sales teams that want multichannel sequences — something GMass doesn’t offer.

Pricing: the Email plan costs $69/month. The Multichannel plan costs $109/user/month. There’s a 14-day free trial. See our guide to lemlist pricing.

Pros of lemlist

• Multichannel sequences: combine email, LinkedIn, and calls in one campaign.
• Advanced personalization: custom images, videos, and landing pages for each prospect.
• Warm-up included: deliverability tools come with the paid plans.

Cons of lemlist

• Much pricier than GMass: especially on the per-user Multichannel plan.
• Overkill for simple mail merge: if you just want personalized emails with follow-ups, it’s more tool than you need.

6. Mailshake

Mailshake is a sales engagement tool for small sales teams. It covers cold email sequences, and its top plan adds a phone dialer and LinkedIn automation.

Best for: small sales teams that want email outreach and calls in one place.

Pricing: plans are billed per user. Starter costs $29/user/month, Email Outreach costs around $49 to $59/user/month depending on billing, and Sales Engagement costs $99/user/month.

Pros of Mailshake

• Works with Gmail and Outlook: unlike GMass, you’re not tied to one email provider.
• AI writing assistant: helps you draft outreach emails faster.
• Phone dialer and LinkedIn steps: available on the Sales Engagement plan.

Cons of Mailshake

• Per-user pricing: costs grow with each team member.
• Limited entry plan: Starter includes one email address and a capped number of monthly sends.
• Built for sales: not the best fit for newsletters, internal updates, or school and nonprofit emails.

7. Woodpecker

Woodpecker is a cold email platform focused on deliverability. Warm-up, email verification, and bounce protection come included, and it works with Gmail, Outlook, and other providers.

Best for: founders and small teams running careful, targeted cold email campaigns.

Pricing: Woodpecker charges by the number of prospects you contact each month, at about $7 per 100 prospects. Contacting 500 prospects per month costs around $35/month, with a discount on annual billing. LinkedIn automation is an add-on.

Pros of Woodpecker

• Deliverability tools included: warm-up, verification, and bounce protection on every plan.
• Works beyond Gmail: connect Gmail, Outlook, or other email accounts.
• Integrations: connects with popular CRMs and tools like Zapier.

Cons of Woodpecker

• Costs grow with your list: you pay more as you contact more prospects each month.
• LinkedIn costs extra: multichannel outreach requires a paid add-on.
• No free plan: only a free trial.

How to Choose the Right GMass Alternative

Start with the reason you’re leaving GMass. Then pick the tool that fixes it:

• You want the same mail merge experience for less, or you use Outlook: go with Mailmeteor.
• You only send simple mail merges a few times a year: go with YAMM.
• You need to send cold emails at high volume across many inboxes: go with Instantly or Saleshandy.
• You want LinkedIn and calls in your sequences: go with lemlist or Mailshake.
• You want deliverability-first cold email on a small list: go with Woodpecker.

If you mainly email people who know you — clients, partners, members, students — you probably don’t need a cold email platform. A mail merge tool that sends from your own inbox will feel more personal and cost far less.
