Dynasend vs Opensense (2026): which should you pick?

Pick Dynasend if

• Fits if you run Microsoft 365 for 30 to 50 people and want the setup done for you
• Works for firms that want a flat fee under 50 signatures

Look elsewhere if

• Skip it if you use Google Workspace or Gmail, which the pages do not list
• Pricey if you are a handful of people, as the floor is $50 a month
• Watch out: a credit card is needed first, with manual invoicing only on request
• Watch out: above 50 signatures it is $1.00 down to $0.55 each, and over 2,000 is by quote
• Too light for end-user support, because help covers the admin side only

Pick Opensense if

• Fits if you're a large organization that wants IT-controlled signatures on Microsoft 365, Google Workspace or Exchange
• Works for US government contractors on Microsoft's GCC High cloud

Look elsewhere if

• Not for you if you're a small company: every plan has a $500 monthly minimum
• Watch out: every plan also needs a service plan whose price isn't on the pricing page
• Skip it if you want to try it without a sales call, as trials go only to accounts qualified through a demo
• Pricey if you want email tracking too, which is a separate line of plans from $20 to $65 a user a month
• Watch out: GCC High costs $2 more a user a month, and account and deal-stage targeting need Complete at $5

Dynasend

• It supports Microsoft 365 and Outlook only; the pages list no Google Workspace or Gmail support.
• Above 50 signatures it charges per active signature: $1.00 for 51-100, $0.93 to $0.60 across 101-500, $0.55 for 501-2,000; over 2,000 is by quote.
• Technical support covers the admin portal, add-in, Entra ID, SSO and billing; direct end-user support is not provided.
• The FAQ says a credit card is needed first to set up the Stripe payment profile, with manual invoicing available on request.

Opensense

• Every plan has a $500 monthly minimum, and Opensense says a small company is better served by a free generator.
• Plans also need a service plan whose price is not published on the pricing page.
• Email tracking is a separate line of plans from $20 to $65 per user a month, with the same $500 minimum.
• Trials are offered only to accounts Opensense qualifies, through a demo.

Dynasend

Full-service setup

The vendor builds the program: database structure, HTML templates and locations, and can convert an existing signature design. The admin provisions an Entra ID sync and deploys the Outlook add-in.

Signatures on every Outlook client

Supported clients listed are Outlook for Microsoft 365 on Windows and Mac, Outlook on the web, and the Outlook mobile apps on iOS and Android.

Three signature levels

Separate signatures can be used for new messages, replies and forwards, and internal email, and the add-in can enforce the company signature on every message.

Banner and note campaigns

Banner campaigns can be scheduled and aimed at role-based groups, and the platform also lists schedulable notes, relocation messages and one-click feedback or CSAT surveys.

Control over user edits

Admins decide which data fields users may change, from none to all, through a user portal.

Digital business cards

Wallet passes for iOS and Android carry a personal QR code and stay in sync with the data in the email signature.

Opensense

Central deployment

Signatures are pushed by transport rule, Outlook add-in or both, with in-client previews, and work in Outlook, Gmail and Apple Mail on desktop and mobile.

Targeted banner campaigns

From Pipeline, schedule banners by department and A/B test them; Complete targets them by account, deal stage or individual recipient using CRM data.

Recipient-level insights

Reports deliveries, impressions and clicks on banners per recipient and per employee.

Directory, HR and SSO

Every plan syncs from Azure AD or Google Directory; Pipeline adds HR systems such as Workday and BambooHR and SSO through Okta, OneLogin, Ping or SAML.

GCC High support

Runs on Microsoft's GCC High cloud for regulated US federal organizations, for $2 more per user a month on any plan.

Onboarding included
