We read Mailshake's reviews on 11 October 2026. G2 rates it 4.7 out of 5 from 376 reviews, and Trustpilot 4.7 from 100, where Trustpilot adds that Mailshake “hasn’t invited customers recently, so reviews may not be representative”. It bills per user, and its three priced plans connect 1, 2 or 10 email addresses per user, with no free trial. The complaints we found are too few mailboxes to send at volume, paying before you can try it, and an interface that takes extra clicks.

These are three complaints Mailshake reviewers raise, and what Emailchaser does about each.

Two mailboxes are too few to send at volume.

“Would have like at least one more account since a campaign of any meaningful size will go out very slowly with only two email accounts.”G2, 4.5 stars, 28 Apr 2026
On EmailchaserConnect as many email accounts as you like on every plan, and each campaign spreads its sends across them, every mailbox within its own daily limit. On Mailshake, 10 mailboxes take the Sales Engagement plan at $99 a user a month, so a team of three with 10 each pays $297. Emailchaser Pro is $97 for the whole team.

You pay before you can find out whether it suits you.

“I worked out the product wasn't for me and didn't work as I expected it to within days and now find myself having to pay $1k / seat for a product I won't use.”Trustpilot, 1 star, 25 May 2023
On EmailchaserEvery plan starts with a 7-day free trial: try any plan free for a week, and if you cancel before the trial ends you are not charged. Asked whether it has a free trial, Mailshake's own pricing page answers: “No, we collect payment up front.”

The interface feels dated and takes extra clicks.

“the UI/UX could definitely be smoother; some flows take extra clicks and feel less intuitive than they should.”Trustpilot, 4 stars, 18 Feb 2026
“The interface feels outdated and like 90s.”G2, 4 stars, 14 Jan 2026
On EmailchaserAutopilot does the clicking for you: give it your website and it drafts the sequence, then finds the prospects and launches the campaign once you approve it. While it runs, it tops up prospects and shifts sends toward the versions that win.

This is what Mailshake reviewers like, and Emailchaser does it too.

A new account can launch a campaign right away.

“You can start with a new account and launch revenue generating cold email campaigns immediately.”G2, 5 stars, 7 May 2026
On Emailchaser tooGoogle and Microsoft mailboxes connect with a sign-in, with no passwords to paste, and Write with AI drafts your first email and every follow-up in one go.

Follow-ups stop the moment someone replies.

“Being able to “set and forget” the second rounds while knowing they’ll stop the moment someone replies makes my job so much easier.”Trustpilot, 5 stars, 22 Apr 2026
On Emailchaser tooStop on reply is on by default: a lead who replies drops out of the sequence, and so does everyone else at their company. An out-of-office reply can pause a lead until the date they're back.

A separate space for each client.

“It is super useful for our company, as we serve many different clients and can create a unique team for each of them.”G2, 4 stars, 5 Mar 2026
On Emailchaser tooOpen a workspace for each client, with its own mailboxes, leads and campaigns, and it runs on your plan at no extra cost. Mailshake's pricing page recommends that each client create their own team and be the billed party.

Our verdict: Mailshake is simple and well liked, but its per-user plans cap how many mailboxes you can send from.

  • G2 and Trustpilot both rate it 4.7, from 376 and 100 reviews, mostly for how easy it is to use and for its support.
  • It bills per user, its priced plans connect 1, 2 or 10 email addresses per user, and it takes payment before you can try it.
  • A team of three with 10 mailboxes each pays $297 a month on Mailshake and $97 on Emailchaser Pro, where unlimited mailboxes and seats, warm-up and the Unibox are all in the plan.
