The Yesware Plugin: Three Surfaces, Two Compatibility Lists and One Tier Gate

Yesware's install page offers no download link. It offers two buttons, Sign In with Microsoft and Sign In with Google, and which one you press decides which of three different products you end up running. They are not the same artefact in different wrappers, and their compatibility lists do not match.

That is the practical question behind most searches for the Yesware plugin, and the vendor answers it across three separate pages rather than one. Everything below is verified against yesware.com's own install, platform and pricing pages, fetched 16 August 2026. We run Email Bison for sending, so this is a documentation read of another vendor's product rather than an account of using it.

Three surfaces, not one plugin

Yesware describes itself as working in the background of the email client you already use. In practice that means three distinct installations, and a team split across email clients is running two deployments rather than one.

The Gmail surface is a Chrome extension. Yesware's Gmail platform page describes it as adding tracking, templates, scheduling and analytics inside Gmail, and states compatibility as all G Suite accounts and Gmail.com accounts using the latest version of Chrome. That is a narrow statement worth reading literally: the browser is named, and no other browser is.

The Outlook surface is an add-in with its own installation path. Its compatibility line is the more interesting of the two: Outlook Desktop 2016 or above, and Outlook on the Web using the latest version of Chrome, Edge or Internet Explorer. A named dependency on Internet Explorer on a page served in 2026 tells you how long that list has gone unrevised, which is a reasonable thing to raise with a vendor before a rollout rather than after one.

The Salesforce surface is a sidebar rather than a browser install, and it is gated by plan rather than by client. More on that below, because it is the surface people assume comes with the others.

Salesforce sidebaryesware.com/plans-and-pricing

• Inbox sidebar with Lead, Contact, Account and Opportunity records

• Listed on the Enterprise tier only

The Salesforce integration is a tier, not a feature

Yesware's Outlook page describes the Salesforce integration in appealing terms: daily activity syncs into the CRM automatically, and Lead, Contact, Account and Opportunity records can be created, edited or viewed without leaving the inbox.

The pricing page settles where that lives. Salesforce Inbox Sidebar, Salesforce Email Sent Sync, Salesforce Email Reply Sync, Salesforce Calendar Sync, Salesforce Background Sync, bi-directional activity sync, adding contacts to campaigns from Salesforce, importing list views into campaigns, Salesforce single sign-on and trusted IP ranges are all listed on the Enterprise plan, published at $85 per seat per month on monthly billing and $65 per seat on annual billing.

That matters for two reasons. The first is budget: a team buying Yesware primarily for CRM logging is buying the top tier, not the entry one, and the per-seat gap between the mid and top tiers is the real price of the integration. The second is scope. Sync features described in prose on a marketing page and listed as line items on a pricing page are exactly the class of thing to get confirmed in writing, because activity sync means different amounts of work at different vendors.

The plan ladder around it runs Free at $0, Pro at $19 per seat monthly or $15 annually, Premium at $45 monthly or $35 annually, and Enterprise at $85 monthly or $65 annually. Both billing states are rendered into the same page, so the state is named beside every figure here.

The number that surprises an outbound reader

Yesware's plans carry a limit that has nothing to do with the plugin and everything to do with whether the product suits the job: campaign recipients per month.

The Free plan allows ten campaign recipients a month. Pro, at $19 per seat monthly, allows twenty. Unlimited campaigns appear at Premium, $45 per seat monthly.

Anyone arriving from a cold-outreach question should sit with those figures for a moment. Twenty campaign recipients a month is a tool for a seller working a named list, adding a handful of people to a sequence each week. It is not a volume instrument, and reading the tracking features as an outbound engine misreads the product.

The tracking side is where Yesware is strong and where the caps loosen: unlimited email open tracking, link tracking and attachment tracking all arrive at Pro. That combination, generous tracking with tight campaign volume, is a clear statement about who the product is for.

Before the rollout

• ✓Yes: Decide which client each person uses, since the Gmail extension and the Outlook add-in are separate installs.
• ✓Yes: Check browsers against the stated lists, which name Chrome for Gmail and Chrome, Edge or Internet Explorer for Outlook on the Web.
• ✓Yes: Confirm Outlook Desktop is 2016 or above, which is the stated floor.
• ~Depends: Price the Salesforce sidebar as the Enterprise tier rather than as an add-on.
• ✓Yes: Read the campaign-recipient caps before assuming the tier covers outbound volume.
• ✓Yes: Take the operator name into the security review, since the site is now branded with Vendasta.
• ✕No: Assume feature parity between the browser extension and the Outlook add-in.

Who you are actually installing

A browser extension or a mail add-in runs inside the client that holds your correspondence, so the identity of the party operating it belongs in the security review alongside the permissions.

Yesware's own pages answer that question, and the answer has changed. The logo asset served across yesware.com is a combined Vendasta-Yesware mark, a Vendasta logo appears in the same page furniture, and the contact block on the pricing page gives the address as Vendasta Square Headquarters, 410 - 22nd Street East, Floor 15, Saskatoon, Saskatchewan, Canada.

None of that is hidden and none of it is a problem in itself. It is simply the kind of detail a security questionnaire asks for, and a procurement document naming a different company than the one on the website is an avoidable delay. The Chrome Web Store listing's title carries the same combined branding, which is where most people first notice it.

A note on that store listing as a source. Fetched with a plain script, the Chrome Web Store returns a page whose listing details render client-side and are absent from the served bytes, so no version, user count or rating is quoted here. A store page that will not yield its details to a fetch is a statement about the fetch, not about the extension.

The permission scopes are the other half of that review, and they are worth reading in the browser's own install dialogue rather than from any page, because that dialogue is the authoritative statement of what the extension can reach. Install on the account that will actually use it rather than on a personal profile signed into a work address, and read the prompt while it is open.

1. Step 1Split the team by client

   Gmail users take the Chrome extension; Outlook users take the add-in, which is a separate artefact.

2. Step 2Check the versions

   Outlook Desktop 2016 or above, and the browser lists the vendor names for each surface.

3. Step 3Clear the admin path

   Workspace and Microsoft 365 policy can block an install, which is a policy fix rather than a reinstall.

4. Step 4Install on one machine first

   Read the permission dialogue there, on the account that will really send.

5. Step 5Confirm the tier

   The Salesforce sidebar and unlimited campaigns are plan-gated, so verify before the rollout, not after.

Where this sits against outbound at volume

The plugin model puts the tool where the person is. Every seat needs its own install, every new laptop needs it again, and the sending identity is a real person's mailbox rather than a pooled resource. For named reps working named accounts, that is exactly right, and it is why this category clusters around tracking, templates and scheduling.

It also means the model does not extend to volume sending, for architectural reasons rather than commercial ones. Cold volume comes from spreading messages across many mailboxes each sending modestly, which is what inbox rotation describes, and a plugin sitting in one person's inbox has no pool to rotate across. The constraint that actually governs the ceiling is the mailbox provider's own, which sending limits by provider catalogues, and the estate that carries real volume is covered in cold email infrastructure.

If the evaluation is heading toward a different shape of tool, cold email software sets the architectures side by side and the Yesware alternatives roundup covers the direct swaps.

One position worth stating as our own policy rather than as a comment on the product. We run one message per campaign, with no bumps and no thread replies, and we send from dedicated infrastructure rather than from the mailboxes we correspond from. Tracking-led tools make it easy to treat an open as a reason to send again, and an unanswered message followed by another unanswered message is volume without information, which is what mailbox providers filter on.

What to take away

The Yesware plugin is three products: a Chrome extension for Gmail, an add-in for Outlook with its own compatibility list, and a Salesforce sidebar that is a plan tier rather than an install. Check the client split first, because it decides how many deployments you are actually running.

Read the campaign-recipient caps before assuming the tool fits outbound, since the entry paid tier allows twenty a month. Price the Salesforce integration as Enterprise. And take the Vendasta name into the security review, because the site now carries it and your procurement paperwork will need it.

If the constraint is the number of companies willing to take a meeting rather than the tracking on the ones you already email, see what a first campaign looks like, booked against a qualification standard agreed in writing before launch.
