Outsolvi vs Streak: the best Streak alternative in 2026
Updated October 10, 2026
Quick answer
Pick Streak if your team works only in Gmail and wants a CRM inside the inbox; its free plan already tracks opens and clicks and runs mail merge with follow-ups. Pick Outsolvi if anyone sends from Outlook, since Streak runs only in Gmail, or if you need to know whether a person or a machine opened the email. Outsolvi grades every open and shows the reason. It costs $7 a month billed yearly for one person, or $20 per person on Pro. Streak's CRM starts at $49 per user a month billed yearly.
Streak is a CRM built into Gmail. Its own site calls it a "Gmail CRM for High-Performing Teams", and it has been building inside Gmail since 2011. Pipelines, contacts, tasks, reports and AI features sit next to the inbox, and email and link tracking come on every plan, including the free one (pricing page, checked 10 Oct 2026).
Streak runs in Gmail only, in Chrome, Safari and Edge. Asked about an Outlook plugin, its FAQ says the team "can't dedicate our resources to it at this time". That answer was written in March 2019 and was still live when we checked on 10 Oct 2026. If anyone on your team sends from classic Outlook, new Outlook or Outlook on the web, Streak doesn't run there.
On tracking, Streak's help center is candid. It calls tracking "fallible", says to treat link clicks as "directional rather than perfectly comprehensive", and says that if you read your own sent email on "any tablet/phone, we will register a view." Its pages don't mention Apple Mail Privacy Protection, security scanners or bots (checked 10 Oct 2026). Outsolvi grades every open as a person or a machine and shows the reason, so Apple Mail preloads, scans and your own re-reads are shown but not counted.
Price depends on what you need. For a Gmail-only rep, Streak's free plan tracks opens and clicks and allows 50 mail merge sends a day, which costs less than Outsolvi. The CRM starts on Pro at $49 per user a month billed yearly ($59 monthly), and Streak says "Everyone on a Streak team must be on the same plan." Outsolvi is $7 a month billed yearly ($12 monthly) for one person and up to 250 tracked emails a month, or $20 per person a month billed yearly ($29 monthly) on Pro, with no cap.
Streak is a CRM inside Gmail, with tracking and mail merge on every plan, including free. Outsolvi is email tracking and follow-up for Outlook and Gmail that grades every open as a person or a machine and shows why. Gmail only and you want a CRM: Streak. Anyone on Outlook, or you need to know who actually read it: Outsolvi.

Why teams choose Outsolvi
Outsolvi is built for people who send one-to-one from Outlook or Gmail and want to know who actually read it: AEs, founders, SDRs and consultants. It runs in classic Outlook for Windows (desktop add-in), Outlook on the web and new Outlook (web add-in) and Gmail, in one product. Streak doesn't run in Outlook: asked about an Outlook plugin, its FAQ says the team "can't dedicate our resources to it at this time". Every open in Outsolvi is graded as a person or a machine, and the reason is shown in plain words: "reached an Apple Mail inbox", "Microsoft Defender security scan", "Gmail preloaded this", "your own open". The machines are shown but not counted, so the opens you act on are the ones a person most likely made. Follow-ups run up to 3 steps and stop when the person replies by email. And if you don't want a CRM, you don't pay for one: $7 a month billed yearly for one person, $20 per person a month on Pro.
Where Streak excels
Streak is the better choice if your team works only in Gmail and wants a real CRM there: pipelines, boxes, contacts, tasks that sync to Google Calendar, reports and AI autofill, with automations and integrations on Pro+. Its free plan is generous for a solo Gmail user: email and link tracking, snippets and mail merge with automatic follow-ups, 50 sends a day, for $0. Mail merge follow-ups stop on reply by default, and out-of-office replies are ignored by default, so an auto-reply doesn't end the sequence. It shows city-level location and device type for each view, runs in Chrome, Safari and Edge, and has iOS and Android apps. Its help center says "Streak does not store the contents of your emails." And it has been building inside Gmail since 2011, "still independent, still profitable" by its own account.
Same email, two trackers
One cold email's first minutes, event by event. A tracker that counts every event and Outsolvi's labels drift apart fast, and only one of them tells you who's worth a follow-up.

Streak's prices are per user per month in USD, from its pricing page on 10 Oct 2026; yearly billing is "20% off". The free plan already includes email and link tracking and mail merge with automatic follow-ups (50 sends a day), so for a Gmail-only rep who doesn't need a CRM, Streak costs less than Outsolvi, and Outsolvi Individual covers one person and 250 tracked emails a month. Streak says everyone on a team must be on the same plan. Enterprise ($129 yearly, $159 monthly) is left out of the table. Streak's trial is 14 days of Pro+.

Which is right for your team
Honest framing of who each tool fits best. Not every team is the same buyer.
AE who sends from classic Outlook, new Outlook or Outlook on the web
Wants every one-to-one email tracked and follow-ups that stop on reply, without leaving Outlook. Asked about an Outlook plugin, Streak's FAQ says the team "can't dedicate our resources to it at this time" (checked 10 Oct 2026). Its install dialog lists Chrome, Safari and Edge.
Outsolvi. It runs in classic Outlook for Windows (desktop add-in) and in Outlook on the web and new Outlook (web add-in), so tracking and follow-ups live where the AE writes.
Team with some reps on Outlook and some on Gmail
The manager wants one place to see who actually read what, across both inboxes. Streak calls itself a Gmail CRM, and none of its pages we checked on 10 Oct 2026 offer an Outlook product, so the Outlook reps' emails would sit outside it.
Outsolvi. One product across Outlook and Gmail, with every open graded the same way on both.
Founder who re-reads their own sent emails on the phone
Checks the Sent folder between meetings before deciding who to chase. Streak's help center says it blocks your own views only in a Chrome browser with Streak installed; on "any tablet/phone, we will register a view." (checked 10 Oct 2026).
Outsolvi. A sender's own re-reads are labelled "your own open" and left out of the count, so your reads don't look like their interest.
SDR whose prospects use Apple Mail or sit behind a security gateway
Needs to know whether an open was a person or a machine before picking up the phone. Streak's help center calls tracking "fallible" and says location can come from "an intermediary server". Its pages don't mention Apple Mail Privacy Protection, security scanners or bots (checked 10 Oct 2026).
Outsolvi. Every open is graded as a person or a machine with the reason shown, such as "reached an Apple Mail inbox" or "Microsoft Defender security scan", and the machines aren't counted.
Gmail-only founder with no CRM yet
Wants pipelines, contacts, tasks and mail merge in the inbox, without another tab. Streak Pro is $49 per user a month billed yearly ($59 monthly) and adds shared pipelines and up to 1,500 mail merge sends a day (400 for consumer Gmail accounts).
Streak. A CRM inside Gmail is what it's built for. Outsolvi isn't a CRM and won't replace one.
Solo Gmail rep on a $0 budget
Sends from Gmail only and wants opens, clicks and a simple follow-up without paying. Streak's free plan lists "Email & Link Tracking" and "Mail Merge (50/day)", and its pricing page describes mail merge as sending "with automatic follow-ups" (checked 10 Oct 2026).
Streak free, honestly. It costs less than Outsolvi and allows more volume. Outsolvi is worth $7 a month only if you need to know whether a person or a machine opened the email, or you send from Outlook.
Switching from Streak to Outsolvi
What to expect, in order. The 14-day Outsolvi trial covers the whole switch.
Day 0: decide what Streak does for you
If Streak is only your tracker, nothing needs to move. If it is your CRM, choose where pipelines and contacts will live next and move them before you cancel: Outsolvi isn't a CRM and won't hold them. The full 30-day plan is at /migrate/from-streak.
Day 1: install Outsolvi where you send
Classic Outlook for Windows: the desktop add-in (installing it needs admin rights). Outlook on the web and new Outlook: the web add-in. Gmail: the Chrome extension. Then send your next one-to-one email as you normally would.
Days 1 to 14: watch the reasons
Each open in Outsolvi shows whether it was most likely a person or a machine, and why. Use the trial to see how many of your opens were preloads, scans or your own re-reads, and whether that changes who you follow up with.
Day 14: decide
The trial ends at 14 days or 250 tracked emails, whichever comes first, with no card. If you were paying for Streak Pro mainly for tracking, compare it with Outsolvi Pro at $20 per person a month billed yearly. If you use Streak's CRM, keep it.
Frequently asked questions
Does Streak work in Outlook?+
No. Streak runs in Gmail, in Chrome, Safari and Edge. Asked about an Outlook plugin, its FAQ says the team "can't dedicate our resources to it at this time" (article from March 2019, still live on 10 Oct 2026). Outsolvi runs in classic Outlook for Windows, Outlook on the web, new Outlook and Gmail.
Is Streak's email tracking free?+
Yes. "Email & Link Tracking" is on Streak's free plan and every paid plan, per its pricing page (checked 10 Oct 2026). The free plan also includes snippets and mail merge, up to 50 sends a day. Streak says "The free plan does not include CRM pipelines."
How much does Streak cost compared with Outsolvi?+
Streak, per user per month (pricing page, 10 Oct 2026): Free $0; Pro $49 billed yearly or $59 monthly; Pro+ $69 or $89; Enterprise $129 or $159. Outsolvi: Individual $7 a month billed yearly or $12 monthly for one person and up to 250 tracked emails a month; Pro $20 per person a month billed yearly or $29 monthly, no cap. For 5 people billed yearly, that's $245 a month on Streak Pro and $100 on Outsolvi Pro. For one Gmail user who doesn't need a CRM, Streak free costs less.
Does Streak store my email content?+
Streak's help center says "Streak does not store the contents of your emails." It says it stores metadata for emails you share with your team (support article updated about 21 Sep 2026, checked 10 Oct 2026).
Does Streak count my own opens?+
Sometimes. Streak's help center says it blocks your own views only when you read your sent email in a Chrome browser that also has Streak installed. On another computer, browser, tablet or phone, it says "we will register a view." Outsolvi labels a sender's own re-reads "your own open" and leaves them out of the count.
Does Streak filter out Apple Mail Privacy Protection or scanner opens?+
Its pages don't say. We found no mention of bots, Apple Mail Privacy Protection or security scanners on Streak's pages (checked 10 Oct 2026). Its help center says "Like all email tracking tools, it is fallible" and calls link clicks "directional". Outsolvi grades every open as a person or a machine, shows the reason, and leaves the machines out of the count.
Can Streak send automatic follow-ups?+
Yes, through mail merge, on every plan. By default, follow-ups stop when a recipient replies, and out-of-office replies are ignored, so an auto-reply doesn't stop them. Free is limited to 50 mail merge emails a day; paid plans to 1,500 (400 for consumer Gmail accounts). Outsolvi follow-ups run up to 3 steps and stop when the person replies by email.
Does Streak have a free trial?+
Streak has a free 14-day trial of its Pro+ plan, and a free plan with no end date. Outsolvi's trial runs 14 days or 250 tracked emails, whichever comes first, with no card.
Is Outsolvi a CRM like Streak?+
No. Outsolvi is email tracking and follow-up for Outlook and Gmail. If you want pipelines, contacts and deal records inside Gmail, Streak does that and Outsolvi doesn't. If you already have a CRM, Outsolvi sits next to it rather than replacing it.
The fastest answer is the 14-day free trial against your real send volume. No credit card, setup in 2 minutes.
Streak is the better tool for a Gmail-only team that wants its CRM inside the inbox, and its free plan is hard to beat for a solo Gmail user who needs basic tracking and mail merge. Outsolvi is the better tool for anyone who sends from Outlook, since Streak runs only in Gmail, and for anyone who needs to know whether a person or a machine opened an email before deciding who gets a follow-up. If you pay for Streak Pro mainly for its tracking, compare $49 per user a month with Outsolvi Pro at $20, both billed yearly.
Our honest take on Streak
Our take: Streak and Outsolvi only look like rivals because both put tracking in your inbox. Streak is a CRM. Tracking is something it gives away on the free plan, and its help center is unusually candid about the limits: tracking is "fallible", link clicks are "directional", and a read of your own sent email on your phone registers as a view. If you live in Gmail, want a CRM and rarely make a call based on an open, our honest advice is to stay on Streak.
Where we think it stops working for the people we build for is the first time a deal touches Outlook. An AE at a Microsoft shop, a consultant who writes from new Outlook, a team that just hired two reps who prefer classic Outlook: asked about an Outlook plugin, Streak's FAQ has said since March 2019 that the team "can't dedicate our resources to it at this time". That's a reasonable call for a Gmail CRM. For someone who sells from Outlook, it ends the comparison.
The second gap is quieter. If you decide who to follow up with based on opens, you need to know which opens were people. Streak's pages don't mention Apple Mail Privacy Protection, security scanners or bots (checked 10 Oct 2026), so that judgment is left to you. Outsolvi puts a reason next to every open and leaves the machines out of the count. That's the job we think a tracker should do, and it's the one a CRM has little reason to prioritise.
