Streak's Mail Merge Is 1,500 a Day on Every Tier — Including the $129 One

Three paid tiers, and one of the headline numbers is identical across all of them:

Enterprise costs roughly 2.6× Pro and sends exactly the same volume.

So if you are upgrading to email more people, stop — the upgrade does not do that. What Enterprise buys is AI credits and whatever administrative features sit alongside them, and the sending capacity you already had on the cheapest paid plan.

That is a genuinely useful thing to know, because "we're hitting limits, let's upgrade" is the reflex, and here it would be a purchase that changes nothing about the limit being hit.

The pricing page discloses something most vendors would leave you to discover:

Personal Gmail accounts are limited to 400 emails/day due to Google's sending limits.

So the real ceiling is whichever is lower — Streak's 1,500 or Google's 400. On a personal `@gmail.com` account, you will never reach 1,500, because Google stops you at 400 first.

Streak is a layer inside Gmail; it cannot exceed what Gmail permits. Publishing that plainly is honest, and it means the 1,500 figure applies to Google Workspace accounts rather than to everyone reading it.

Check which account type you are on before pricing this, because on a personal account the sending allowance you are buying is not the one advertised.

With sending flat, credits are what the tiers sell:

• Pro — 20 per user per month
• Pro+ — 150 (7.5×)
• Enterprise — 500 (25×)

Twenty credits a month on Pro is a handful of AI actions — enough to try the feature, not to build a workflow on. If AI drafting or enrichment is why you are here, Pro is effectively a demo of it.

That makes the tier decision unusually clean: you are choosing an AI credit budget. Everything else about sending is constant.

The page does not state the cost of additional credits, so if you expect to exceed your tier's allowance, that is a question for sales before committing.

The page states you can "use our email power tools for free, forever" — but does not state the limits of that free tier.

An unquantified free plan is difficult to plan around. It is clearly not a full CRM tier, and how much mail merge, tracking or pipeline access it includes is not published.

Treat it as worth installing and testing rather than as a specification. A previous version of this review called it "a solid free plan"; that judgement was not supportable from a page that does not say what the plan contains, and it has been removed.

Each tier displays two figures — Pro at $49 and $59 per user, Pro+ at $69 and $89, Enterprise at $129 and $159 — with the higher number labelled annual.

An annual rate above the monthly rate is backwards, and both cannot be right. Rather than guess which way round it is, the honest statement is that the page's monthly/annual labelling is contradictory as published — check the toggle at checkout.

Every figure quoted in this review is taken from the page as listed. The lower number in each pair is used as the entry price on the assumption that it is the cheaper of the two, which is the only claim that holds either way.

If your team does not live in Gmail, the entire architectural premise is gone. Streak's value is being inside the inbox; outside Gmail there is nothing to be inside.

If you need sending volume, this is not the category. 1,500 a day is a mail merge allowance for personal outreach, and no tier here raises it — a dedicated email platform is the right tool.

Living inside Gmail is a real advantage for teams whose work already happens there, and the disclosure of Google's own 400/day limit is more candid than most vendors manage.

But do not upgrade for volume — every paid tier sends 1,500 a day. The ladder is an AI credit ladder: 20, 150, 500. Decide how many credits you need, check whether you are on a personal or Workspace account, and confirm the billing toggle at checkout.

The 1,500-per-day mail merge limit on Pro, Pro+ and Enterprise; the AI credit allowances of 20, 150 and 500 per user per month; the disclosure that personal Gmail accounts are limited to 400 emails/day by Google; the free-forever email power tools; and the paired per-user figures of $49/$59, $69/$89 and $129/$159 are all from Streak's own pricing page, checked 11 August 2026. The free tier's limits, the cost of additional AI credits, and users included per plan are not stated, and the monthly/annual labelling on that page is self-contradictory.
