EmailQo vs GMass

Who GMass is built for

GMass is a Chrome extension that plugs into Gmail. It adds mail merge, sequence automation, reply detection, and analytics directly into the Gmail compose window. Setup takes minutes: install the extension, connect your Gmail account, import contacts from a Google Sheet or paste a list, and you can send campaigns without leaving Gmail. For solo senders who already live in Gmail and want to run small campaigns without a separate tool, it is a fast, low-friction option.

Every paid plan includes sequences, follow-ups, reply tracking, A/B testing, and inbox rotation across multiple Gmail accounts. Standard starts at $29.95 per month or $249 per year. Pricing is per Gmail account, not per person. If you send from three Gmail accounts, you pay three subscriptions.

GMass only works with Gmail and Google Workspace. There is no Outlook support, no native AWS SES integration, and no standalone web app. The Chrome extension requirement ties GMass to a specific browser on a specific machine — there is no mobile app and no way to access campaigns from a different computer without logging in through Chrome. GMass has no built-in email warmup. Google's sending limits also apply regardless of plan: 500 emails per day for regular Gmail accounts, 2,000 per day for Workspace. GMass does not raise those limits. To scale beyond them you add more Gmail accounts or connect an external SMTP provider.

Who EmailQo is built for

EmailQo is built for senders who want to own the infrastructure their campaigns run through. You connect your own Gmail, Outlook, Zoho, or Amazon SES accounts, and EmailQo sends through them directly. Your domain reputation is isolated from every other user on the platform because no one else sends through your accounts.

Before every campaign, EmailQo runs pre-send inbox checks automatically: spam word detection, SPF, DKIM, and DMARC validation, blacklist monitoring, and simulation against enterprise email filters. Problems get flagged before the campaign goes out. Built-in warmup is included on every plan and runs in the background on every connected account. AI reply classification sorts responses into interested, not interested, and out of office, and follow-up sequences pause automatically when someone replies.

The honest limitations: EmailQo has no lead database and no Gmail compose integration. You bring your own contact list. Setup requires configuring your own sending accounts and DNS records, which takes more time than installing a Chrome extension. If you use Amazon SES, AWS bills you separately at $0.10 per 1,000 emails. EmailQo does not mark up that cost, but it is an extra account to maintain.

Pricing at EmailQo is flat monthly: $19 for Starter, $39 for Growth, $89 for Scale. A single plan covers all your connected sending accounts regardless of how many you add.

Pricing per account

GMass at $29.95 per month covers one Gmail account. If you send from multiple accounts, each one needs its own subscription. Two accounts cost $59.90 per month. Three accounts cost $89.85 per month. Annual billing brings the per-account rate to around $20.75 per month, but the per-account model stays the same.

EmailQo at $19 per month covers multiple sending accounts across Gmail, Outlook, Zoho, and SES within one plan. You do not pay more as you add accounts. A team running three Gmail accounts and one SES account pays the same as a solo sender using a single Gmail account.

Side by side comparison

Which one fits your situation

GMass is the right choice for solo senders who live in Gmail and want the fastest path to running campaigns. If you send under 500 emails per day from a single Gmail account, want to use your existing Gmail interface, and are not interested in managing a separate platform, GMass delivers that at $29.95 per month. The setup takes minutes. For individual contributors who want simple mail merge and follow-up sequences without learning a new tool, GMass is genuinely the better fit.

Choose EmailQo if you send from multiple accounts, use or want to use Outlook or SES alongside Gmail, or need warmup running automatically. Adding a second Gmail account to GMass doubles your cost. Adding a second account to EmailQo costs nothing extra. At three or more sending accounts, EmailQo is cheaper from the first month regardless of plan tier.

The absence of warmup in GMass is a practical problem for anyone setting up a new sending domain or account. Running cold email campaigns on a fresh domain without warmup produces deliverability problems quickly. EmailQo runs warmup in the background automatically from the moment you connect an account. If you are launching outreach on a new domain, that difference affects results before the first campaign goes out.
