Outsolvi vs Yesware: the best Yesware alternative in 2026

Yesware's system requirements list Outlook 2016 desktop (v16.0 or later) and Outlook on the web in Chrome or Edge, for mailboxes hosted directly by Microsoft 365. New Outlook for Windows isn't mentioned in its requirements or anywhere in its docs (checked 10 Oct 2026). That doesn't mean it fails there, only that Yesware doesn't say. On a Mac, Yesware asks you to use the legacy Outlook experience, a setting it says resets after 30 days. Outsolvi's web add-in runs in new Outlook and Outlook on the web, and its desktop add-in covers classic Outlook for Windows. Outsolvi doesn't run in Outlook for Mac; on a Mac, send from Outlook on the web.

In part, and it says so. Its docs say it "filters out opens that appear to come from proxies, email security devices" and other infrastructure, so you may see fewer open events. On opens that land the instant you send, its docs say the email may have gone through a virus scanner and "there is no workaround". Its pages don't say whether you can see which opens were filtered or why, and they don't mention scanner clicks (checked 10 Oct 2026). Outsolvi shows every open with a label, such as "reached an Apple Mail inbox" or "Microsoft Defender security scan", and counts the ones graded as a person.

There's a Free plan, labelled "Free Forever" on the pricing page, with open, link and attachment tracking limited to emails sent less than 24 hours ago; the docs say up to 40 events. The same page's FAQ describes the free option as a 14-day trial, and the docs say accounts move to the Free plan after it. Paid plans start at $15 a seat a month billed yearly ($19 monthly). Outsolvi has no free plan: its trial runs 14 days or 250 tracked emails, whichever comes first, with no card.

Yesware Pro allows 20 campaign recipients a month and up to 5 users (pricing page, checked 10 Oct 2026). Premium, at $35 a seat billed yearly, removes the campaign cap; its docs list 900 recipients per upload and 5,000 per campaign. Outsolvi's follow-ups run up to 3 steps per email and stop when the person replies by email.

Not at every team size. Billed yearly, one person pays $7 on Outsolvi Individual (250 tracked emails a month) or $15 on Yesware Pro. Five people pay $75 on Yesware Pro and $100 on Outsolvi Pro, so Yesware is cheaper there, as long as 20 campaign recipients a month is enough. Twenty people can't use Yesware Pro, which stops at 5 users, so the comparison is Yesware Premium at $700 a month against Outsolvi Pro at $400.

Yes, on Enterprise ($65 a seat a month billed yearly, $85 monthly): a Salesforce inbox sidebar, email sent and reply sync, calendar sync, bi-directional activity sync and Salesforce single sign-on. Premium doesn't include it. Outsolvi has no CRM integration, so if Salesforce logging is the reason you use Yesware, that's a reason to stay.

Its pricing table marks Reminders, Send Later and LinkedIn Touches as "Gmail". Its LinkedIn doc says the integration is on Gmail on Premium and Enterprise, needs a Sales Navigator Advanced or Advanced Plus plan, and asks Outlook users to check with support (checked 10 Oct 2026). Outsolvi's follow-ups send from Outlook and Gmail alike, and a sequence can include LinkedIn steps (in early access); an email reply stops those too.

Its docs say it tracks only the To field: "CC'd addresses are not tracked." On an email to several people, it says it "cannot identify exactly who opened it". If you email buying committees, ask any tracker how it reports a group send before you read its counts.
