GMass vs Lemlist
This is close to the widest capability gap of any pair on the site. Lemlist runs multichannel sequences across email, LinkedIn, calls and SMS with a 650M+ lead database behind it, at $69/mo. GMass sends mail merge campaigns from your Gmail window at $29.95. If you are comparing them seriously, the real question is whether you need a sales engagement platform or a better send button.

Hands-on field test
In progressWe plan to run identical 200-contact campaigns from freshly warmed mailboxes on each platform (same copy, same sending window, same domains) and measure inbox-placement rate via seed tests, plus bounce and reply rates. Until that runs we quote no deliverability figures.
The verdict
Lemlist is the far more capable product and priced accordingly — more than double GMass on monthly billing, and per user on its multichannel plan. It earns that only if you will actually use LinkedIn steps, personalisation and the built-in database. GMass does one job, does it inside an interface you already know, and costs $20/mo if you commit annually. Neither is a substitute for the other.
Choose GMass if your outreach is email-only, low-volume, and run from Gmail — paying for multichannel you will not use is the more common mistake. Choose Lemlist if your outbound wins on relevance and multiple touchpoints, or you would otherwise buy a lead database separately.
GMass vs Lemlist: FAQs
- Does GMass do LinkedIn outreach?
- No. GMass is email only, inside Gmail. Lemlist covers email, LinkedIn, calls and SMS in one sequence builder — that is the main thing the price difference buys.
- Which includes email warmup?
- Neither cleanly. Lemlist offers warmup as a paid add-on (lemwarm) rather than including it, and we found no documented warmup feature for GMass. If bundled warmup matters, QuickMail and Mailshake both include it on every plan.
- How big is the price gap really?
- Lemlist is $69/mo monthly, $55/mo billed annually, and its multichannel plan is priced per user. GMass is $29.95/mo monthly or $20/mo billed annually. So roughly double at the entry point, and wider as team size grows.
- Which can I evaluate more easily?
- GMass — no card, no signup form, just the extension. Lemlist offers a 14-day trial that also needs no credit card, so both are testable, but GMass has essentially no friction at all.
