Stannp

Stannp is a direct-mail service for sending personalized postcards, letters and self-mailers through a web dashboard or API. It is best suited to teams connecting physical mail with CRM, ecommerce or application workflows. The main decision is whether its tiered virtual-printer quotas and user limits match your sending volume.

Overview

Campaign creation follows a practical sequence: upload contact data, add a design and schedule the mailing. Stannp says campaigns are printed and mailed the next business day, making it a fit for organizations that need a defined production handoff rather than an entirely manual mailing process.

Customizable engagement reports and real-time campaign insights give marketers a way to monitor response after dispatch. Address verification is supported, and delivery covers domestic and international destinations. The service is available on the web and through an API.

Key features

Stannp combines personalization, scheduling and automation. Its REST API can trigger direct mail from an app, website or CRM, while Zapier, Make.com, HubSpot and Klaviyo integrations provide alternatives for teams that do not want to build every connection themselves. API throughput is plan-dependent, so high-frequency automated sending requires a higher tier.

Support includes a knowledge base, 24/7 webchat, phone and email assistance. Account managers are included on eligible plans, which makes the upper tiers more relevant to organizations needing an ongoing service contact.

Stannp states that it operates in accordance with UK GDPR, the Data Protection Act 2018 and ISO 27001 standards. It describes AES-256 encryption at rest, TLS 1.2/1.3 in transit, role-based least-privilege access, mandatory multi-factor authentication and unique user accounts. Monitoring is backed by a stated 99%+ uptime SLA.

Pricing

The free plan costs $0 per month and allows one user, one template, 50,000 contacts and 20 virtual printer items per month. It has no minimum or maximum send volume, but the small item allowance and single template make it primarily an evaluation or very light-use option.

Starter costs $12 per month. It keeps one user and 50,000 contacts, but raises the template allowance to 10, virtual printer items to 100 per month and adds 300 API requests per minute. This is the sensible entry tier for a solo operator who needs recurring automation without a large catalog of designs.

Growth is $48 per month for five users, 25 templates, 50,000 contacts, 2,500 virtual printer items per month and 600 API requests per minute. It is better suited to a small marketing or operations team; the jump in item capacity is the main practical upgrade over Starter.

Premium costs $315 per month and supports 15 users, 100 templates, 100,000 contacts, unlimited virtual printer items and 2,000 API requests per minute. It targets established programs where monthly item caps would otherwise constrain activity.

Enterprise uses custom pricing and provides unlimited users, unlimited templates, 250,000 contacts, unlimited virtual printer items and 3,000 API requests per minute. Choose it when the Premium seat or contact limits are insufficient and a tailored commercial arrangement is appropriate.

Platforms

Stannp offers web access and an API. The API and integrations make it practical for software-led workflows, while the web interface covers campaign setup and scheduling.

Who it's for

Stannp fits businesses of different sizes, including healthcare, financial services, ecommerce and real estate organizations that need physical mail connected to digital data. It is especially appropriate for teams that value next-business-day production, programmable sending and campaign reporting. A very small sender with occasional mail may find the paid quotas unnecessary, while a growing team should compare its virtual-printer allowance with expected monthly volume.

Pros and cons

Pros

• Multiple automation paths: REST API, Zapier, Make.com, HubSpot and Klaviyo support both custom development and connector-based workflows.
• Broad mail formats: Postcards, letters and self-mailers cover common direct-mail campaigns.
• Operational visibility: Customizable reports and real-time insights help connect sending activity with engagement.
• Strong control and security posture: Multi-factor authentication, role-based access and stated encryption standards suit organizations with stricter data requirements.
• Free starting tier: Users can begin without a subscription and test the workflow before moving to paid capacity.

Cons

• Low free and Starter allowances: 20 and 100 virtual printer items per month respectively can be restrictive for active programs.
• Uneven scaling costs: Unlimited item capacity starts at Premium's $315 per month, creating a substantial gap above Growth.
• Seat and template limits: Teams must move from one user on Free or Starter to Growth or above for collaboration.

Alternatives

Inkit is an alternative for teams focused on signature requests and storage, with a free allowance of three signature requests per month and one seat.

Choose Lob Address Verification when address verification is the primary requirement, with a developer plan starting at $0 per month and usage-based address fees.

Postalytics suits users wanting unlimited campaigns, templates and lists on its free plan, with mail charged per piece.

PostPilot offers a no-cost starting plan with pay-as-you-go postcards and postage plus 10+ analytics reports.

Verdict

Stannp is a strong choice for organizations that want scheduled physical mail, programmable API sending and integrations in one service, with security controls and reporting to support larger operations. Start with Free or Starter for low-volume evaluation, move to Growth for a collaborative team, and choose Premium or Enterprise when item capacity and throughput matter. Look elsewhere if your priority is purely pay-per-piece economics or a lightweight address-verification tool rather than a full campaign platform.
