Dynasend vs Sigsync

Dynasend centrally designs and manages standardized email signatures for Microsoft 365 users and devices. Administrators deploy and update signatures across a tenant through its O365 add-in, without requiring end-user desktop installs. It can create a design or convert an existing one, with variants for new messages, replies, and streamlined messages. Entra ID (Azure AD) sync aligns signature fields with directory attributes, while SCIM provisioning supports user lifecycle management. Multiple templates and unlimited user data fields can serve different brands and divisions. Campaigns can schedule banners, notes, relocation messages, and role-based groups; the platform also offers feedback surveys and digital business cards for iOS and Android. Dynasend says signatures render in Outlook at compose time, data is encrypted in transit and at rest, and it does not access email content or stamp messages in transit. Standard costs $50 a month for up to 50 signatures; above that, monthly per-active-signature pricing varies by volume from 1.00 USD (51–100) to 0.20 USD (18,001+). A 90-day free trial is available.

Sigsync manages email signatures and disclaimers centrally for Microsoft 365 and Exchange. It offers Centralized (Combo), Server, and Client deployment modes. The editor supports drag-and-drop elements, imported HTML, tables, images, social icons, vCards, surveys, and Azure AD fields. Azure AD placeholders can fill signatures with details such as display name, company, job title, department, and profile photo. Server-side signatures work across Outlook, Outlook Web App, Apple Mail, Thunderbird, mobile phones, Macs, and iPhones. Integrations include Office 365, Exchange, Exchange Online connectors, Azure AD, Outlook, and OWA. Marketing tools include promotional banners, scheduled campaigns, analytics, social icons, and CSAT connections with Simplesat and Thermometer. Sigsync states that it uses OAuth 2.0 authentication and TLS encryption, is SOC 2 Type 2 and ISO certified, and complies with GDPR and HIPAA. Licenses are based on users, with no limit on emails sent per licensed user. The monthly plan costs $91 a month; customized pricing is requested for licenses covering more than 200 users. There is a 14-day trial, but no free plan.
