The GMass Startup Guide for Cold Emailers
Everything you need to know to send cold outreach campaigns that break Gmail’s limits and hit the inbox
GMass is one of the most popular cold email platforms on the planet (quite possibly the most popular) with 300,000+ users who’ve given it an average of 4.8/5 stars across 10,000+ reviews.
Here’s your guide to getting started and to thriving with GMass as your cold email platform.
The Basics of GMass
Quickstart Guide
In the quickstart guide you’ll get the GMass Chrome extension set up and connect your Gmail/Google Workspace account to GMass.
Then learn how to create a campaign by connecting a Google Sheet of contacts, mail merging their info, and sending using the GMass button.
More basics?
Get to know the GMass settings box for your campaigns as well as the GMass dashboard where you’ll handle account-level settings.
Breaking Gmail’s Limits
Google sets daily sending limits of up to 500 emails/day for free gmail.com accounts and up to 2,000 emails/day for paid Google Workspace accounts.
GMass offers two methods to get around those limits to send virtually unlimited daily emails.
Method 1: MultiSend inbox rotation
MultiSend, GMass’s inbox rotation feature, allows you to distribute an email campaign across multiple sending accounts, keeping the send volume low for every account.
Plus only your main sending account needs to be a paid GMass account. (Requires Professional or Team plan.)
Method 2: Using a third-party SMTP server
Connect a third-party SMTP service to GMass and when we detect you’ve hit your Gmail daily limit, we’ll use that service to send the rest of your emails.
Send virtually unlimited daily emails from a single email address using this technique.
What if you don’t want to do either?
That’s ok! By default, when you hit your daily Gmail limit, GMass will pause your campaign and resume sending 24 hours later (once your limit resets).
Deliverability
You need your emails to go to the inbox, not the spam folder. GMass’s suite of deliverability tools helps make that happen.
Email verification
GMass has built-in email verification included in your subscription. Just check a single box on your campaign and GMass will validate every address on your list before sending.
Spam Solver
GMass’s unique and powerful Spam Solver actually measures your campaign’s inbox vs. spam rate by sending it to several test accounts — then gives you tips to improve. Use it before you send every campaign!
Tracking off / custom tracking links
Want to have a link-free email? Turn off open and/or click tracking for a campaign in the GMass settings box.
Or better yet, keep tracking on and set up a custom tracking domain. That ensures your sending reputation isn’t affected by other people.
And with GMass automatically adding SSL to custom tracking domains, you can even get a little deliverability boost.
Authentication (SPF, DKIM, DMARC)
Make sure to set up your domain authentication protocols so the mailbox providers know you are who you say you are.

Throttling
Set the speed at which GMass sends your emails, adding pauses between messages, to better mimic a person’s sending cadence.
Spintax
Easily randomize the content in your messages to avoid sending identical or largely identical emails to every recipient using GMass’s spintax feature.
Embedding images
You no longer have to fear using images in cold emails.
Because GMass works natively inside Gmail, you can embed images rather than link to them on a separate server. There’s a real deliverability benefit there.
Automated Follow-Ups
GMass’s auto follow-ups can go out until you get a reply to your campaign.
