GMass alternative with built-in prospect data and AI-written emails
GMass is a mail merge tool that runs inside Gmail. Its individual plans run from Standard at $29.95 a month to Professional at $59.95, with unlimited contacts and campaigns on every plan. ColdReach is a GMass alternative for people who spend more time finding prospects and writing emails than sending them. It builds the prospect list, verifies each address and drafts a personal email for each prospect, then sends from your own mailboxes with ramp-up and daily caps. If you already own a clean list and want cheap bulk mail merge, GMass is a fair buy. If the list and the writing take your week, ColdReach removes that work.
Why people look for a GMass alternative
GMass lives in your Gmail window. You paste or import a list, write a template with merge fields, and it sends and follows up from your own account. That is why it is cheap and why people like it. It is also why it stops there. The sending plans do not come with a prospect database, so the list has to come from somewhere else, and each email is still the template you wrote.
Two limits show up as volume grows. Everything is tied to Gmail, so your sending ceiling is whatever Google allows on that account, and a team with several people on one list needs team pricing that rises with every seat. Teams that hit either limit, or that lose hours every week assembling lists in a separate tool, are the ones who start comparing.

Where GMass wins is price for one person, the familiar Gmail interface and unlimited contacts and campaigns on every plan. Where ColdReach wins is the work before the send.
One plan that covers the list, the check and the email
On ColdReach the target list is built inside the product. You filter by industry, job title, seniority, company size, country and signals from the company website, and every address is verified before it can enter a sequence. Bounced addresses never reach your mailboxes, which protects the domain you send from. Our b2b contact database page explains where records come from, and the email verifier page covers the checks.
A personal email for every prospect
Mail merge swaps a first name and a company into one template. ColdReach drafts a first line and a body that refer to what the prospect's company sells and to whom. You set the tone, edit any draft and approve the first send. On Growth and above you can A/B test subject lines and bodies with our email sequence software. The cold email generator page shows how a draft is built.
Sending that protects your domain
Connect Google Workspace and Microsoft 365 by SMTP and IMAP with an app password. ColdReach ramps mailboxes up gradually, rotates across them, caps each daily and pauses one on its own when bounces or complaints rise. Every email carries an unsubscribe link, and an unsubscribe reply suppresses the contact in every sequence.
What a GMass setup costs next to one ColdReach plan
Take a team of three that needs 2,500 new verified contacts a month with a personal email each. GMass Premium for three people would be around $120 a month at the individual rate of $39.95 per user, and GMass publishes separate team pricing that you should check for your exact seat count. That covers sending, follow-ups, A/B tests and rotation. It does not cover finding 2,500 prospects, and it does not write 2,500 first lines. A separate finder is typically another subscription, and the writing is hours of someone's week.
ColdReach Growth is $149 a month, or $74 billed yearly, for 3 team members, 15 mailboxes, 2,500 verified contacts, 5,000 AI-written emails and 5,000 verifications every month. The list, the check and the writing are already inside that figure. See every limit on our cold email software pricing page, or read the GMass pricing breakdown for each plan and what it leaves out.
Where GMass costs less is a single person with a clean list who writes their own copy. That person should stay.
Who should switch and who should stay
- SDR teams who lose hours to prospect research and first lines: switch, both are included.
- Founders running their own outbound: Starter covers 500 verified contacts and 1,000 AI emails a month for one person.
- Agencies sending for several clients: compare Scale, which includes 10 client workspaces.
- Solo users with an existing list who send newsletters or simple mail merge from Gmail: stay on GMass.
- Teams that live in Gmail and Sheets and want the cheapest possible sender: stay on GMass.
Moving from GMass to ColdReach
Export your contact lists and your unsubscribe list from Google Sheets or Gmail as CSV and import both into ColdReach so nobody who opted out hears from you again. Connect the same mailboxes by SMTP and IMAP. ColdReach starts each mailbox at a safe daily volume, then raises it as reply and bounce rates allow. Rebuild your follow-up steps, then let the AI draft a first email for each imported prospect for review. Still comparing tools? Our best cold email software guide lines up the main options, and the Woodpecker alternative page covers another sender-first tool.
Questions
What is better than GMass
For outbound that needs a list, verification and a personal email per prospect inside one team plan, ColdReach removes more manual work per dollar. For cheap mail merge inside Gmail with unlimited contacts and campaigns, GMass is built for that.
How much does GMass cost per month
GMass lists Standard at $29.95 a month, Premium at $39.95 and Professional at $59.95 for one user on monthly billing, with lower annual prices. Team plans cost more and depend on the number of users. Check its pricing page for current numbers, or read our GMass pricing breakdown.
Is ColdReach cheaper than GMass
GMass is cheaper at the entry for one person. Once you need a team, a prospect list and writing time, ColdReach Growth at $74 a month billed yearly compares well, because the list, the verification and the AI writing are included in the plan.
Does GMass include prospect data
No. GMass sends and follows up on a list you supply. ColdReach builds the list inside the product, verifies every address and records the source and last-checked date for each record.
Can I keep my mailboxes and domains when I switch
Yes. Connect Google Workspace and Microsoft 365 mailboxes by SMTP and IMAP with an app password. ColdReach ramps each one up gradually under a daily cap, so switching does not undo the reputation your domains have built.
