What Sendoso does
Sendoso is a cloud-based corporate gifting and direct mail automation platform that helps B2B revenue teams break through digital fatigue by sending personalized physical gifts, eGifts, branded merchandise, virtual experiences, and handwritten notes to prospects, customers, and employees. Founded in 2016 and headquartered in San Francisco (legal entity: Sender, Inc.), Sendoso serves Sales, Marketing, Customer Experience, and People/HR teams across enterprise and mid-market customers, with named logos spanning VMware, Nutanix, Comcast, Thomson Reuters, Citadel, Gong, Samsara, Gainsight, Verkada, LexisNexis, and others. The platform ships to 165+ countries and has executed over 15 million sends for 800+ global brands.
The product is built around a global gift marketplace, a purpose-built Sendoso Fulfillment Center (not adapted from generic 3PL), and a post-Merch network of 100+ production facilities. An AI layer (SmartSuite — SmartSend, SmartMessage, SmartDelivery — plus the Oso AI Agent and Sendoso MCP for external agents) handles gift recommendations, 1:1 message generation, and address resolution. Sendoso embeds natively into 100+ customer tools across CRM (Salesforce, Microsoft Dynamics 365), sales engagement (Outreach, Salesloft), marketing automation (Marketo, HubSpot, Eloqua), ABM (6sense, Demandbase, RollWorks, Terminus, Bombora), HRIS (Enboarder), ecommerce (Amazon), and surveys (SurveyMonkey). Acquired brands Alyce (Feb 2024), Postal (2025), and Merch (May 2026) have been folded in to consolidate Sendoso's positioning as "the largest corporate gifting and direct mail platform in B2B."
Sendoso operates a primarily sales-led enterprise GTM motion with quote-based subscription tiers (Starter, Core, Advanced, Enterprise), supplemented by a self-serve Starter tier, a merch.sendoso.com storefront, Event Fulfillment services, white-glove Campaign Studio engagements, and channel partnerships (notably INFUSE, Dec 2025). Revenue mechanics blend recurring subscription, usage-based sending/fulfillment fees, per-unit Merch hardware-style revenue, and Campaign Studio professional services. The company is privately held and venture-backed, with $152.7M+ in disclosed funding led by SoftBank Vision Fund 2's $100M Series C in September 2021.

Sendoso competitors and assessment
Company assessmentDirect peers
- Reachdesk: Reachdesk is a direct B2B gifting and direct mail platform competitor, offering similar gift marketplace, CRM integrations, and corporate sending workflows. Closely comparable to Sendoso in product category, target customer (B2B sales/marketing teams), and business model.
- Loop & Tie: Loop & Tie is a B2B corporate gifting platform focused on sustainable gift collections, offering gift choice technology and direct mail services to sales, marketing, and customer success teams — directly comparable to Sendoso's core marketplace and gifting workflow.
- Alyce: Alyce was a direct Sendoso competitor in AI-driven B2B gifting and direct mail before being acquired by Sendoso in February 2024. Pre-acquisition, Alyce offered personal gifting, direct mail, and AI-powered recommendations comparable to Sendoso's SmartSuite.
- Postal: Postal was a Sendoso competitor in direct mail and corporate gifting automation before being acquired by Sendoso in May 2025. Pre-acquisition, Postal offered direct mail logistics and gifting capabilities overlapping directly with Sendoso's offering.
Emerging players
- Lob: Lob is a direct mail automation API platform serving B2B use cases with a developer-first approach. Less of a full-stack gifting platform than Sendoso, but increasingly overlapping on direct mail, programmatic printing, and CRM-triggered mail workflows.
- Handwrytten: Handwrytten specializes in AI-generated handwritten notes and robotically-written cards at scale, directly competing with Sendoso's handwritten notes feature and offering a niche but meaningful overlap with Sendoso's direct mail use cases.
- Tremendous: Tremendous is a global payouts and digital gifting platform used by B2B teams for incentives, rewards, and gift cards. Overlaps with Sendoso on eGift delivery and rewards use cases, but lacks Sendoso's physical fulfillment and AI personalization layers.
- SnackMagic: SnackMagic is a corporate snack and care package gifting platform that overlaps with Sendoso on physical gifting for sales, marketing, HR, and CX use cases, particularly around remote employee engagement and customer gifting.
Broad incumbents
- Salesforce Marketing Cloud: Salesforce Marketing Cloud is a broad incumbent that could natively embed gifting or direct mail features into its CRM/MAP stack — a potential disintermediation risk for Sendoso, which today relies on Salesforce as a primary distribution channel.
- HubSpot: HubSpot is a broad incumbent CRM/marketing platform that could add native gifting capabilities to its Marketing Hub, competing directly with Sendoso for embedded sending workflows in the SMB and mid-market segments.
