ZAP~POST

ZAP~POST turns ecommerce, CRM, and customer-data events into personalized postcard and letter campaigns. It suits teams that want direct mail woven into existing workflows. Its strongest case is automated, recipient-level mail; its costs and delivery terms need checking before a campaign is budgeted.

Overview

ZAP~POST combines event-triggered campaigns with one-to-one personalization, so teams can respond to customer actions without treating every mailing as a standalone task. Its web design app supports drag-and-drop editing, custom fields, uploaded images, and unique promotional or QR codes. That flexibility is useful for tailored campaigns, but teams should plan how they will measure results: QR tracking is available, while conversion attribution is left to the customer’s analytics platform.

Mail formats include oversized and A5 postcards, an A5 one-piece mailer, and secure letters. The company identifies the UK as its main standard mailing location and also supports campaigns in the US, Germany, the Netherlands, France, and Italy. Country-specific specifications, prices, and turnaround vary, so a campaign designed around one market may need adjustment for another.

Key features

Integrations include Klaviyo, Dotdigital, Ometria, HubSpot, Bloomreach, Zapier, Force24, and Shopify. Ecommerce, CRM, and CDP tools can also connect by API, with StackConnect, Zapier, and Patchworks offered as connection options. This makes ZAP~POST a good fit for teams with an existing customer-data workflow; organizations without integration support may need to arrange a connection before automating campaigns.

The service validates recipient data and cleanses records. Rejected records can receive Zap credits under the service’s credit rules, which can help limit wasted sends but does not remove the need to review those rules. ZAP~POST says it is ISO 27001 certified and provides documentation, security policies, and compliance materials through Vanta.

The company says its on-demand mail uses FSC paper from sustainable and recycled sources, biodegradable inks, and recyclable paper. Support is available by email, chat, or phone during UK office hours, with the support provision also varying by plan.

Pricing

The pricing page shows £0 monthly membership figures and “plus from 0p per Zap” across its standard tiers. These figures do not establish a campaign’s postage cost: website pricing is based on second-class mail, while first-class pricing requires contacting the company. The free plan and one-off trial make it possible to explore the service before committing, but teams should confirm country-specific costs and terms before setting a budget.

Monthly Basic is £0 monthly, plus from 0p per Zap, for up to 1,000 Zaps per month, five campaigns, one integration, and email and chat support. It suits small, low-volume programs; the campaign and volume caps constrain growth. Monthly Standard is £0 monthly, plus from 0p per Zap, for up to 2,500 Zaps per month, ten campaigns, one integration, API access and logs, and phone or Meet support. It is a better fit for teams needing API access and more campaign capacity without additional integrations.

Monthly Pro is £0 monthly, plus from 0p per Zap, for up to 5,000 Zaps per month, unlimited campaigns, two integrations, MFA, webhooks and logs, and insights. Monthly Premium is £0 monthly, plus from 0p per Zap, for up to 10,000 Zaps per month, unlimited campaigns and integrations, and a dedicated account manager. Pro suits teams with multiple workflows and a need for operational visibility; Premium is aimed at higher-volume teams that value broader integration access and dedicated support.

Annual Basic is £0 monthly, plus from 0p per Zap, billed annually, for up to 12,000 Zaps per year, five campaigns, one integration, and email and chat support. Annual Standard is £0 monthly, plus from 0p per Zap, billed annually, for up to 30,000 Zaps per year, ten campaigns, one integration, API access and logs, and phone or Meet support. Annual Pro is £0 monthly, plus from 0p per Zap, billed annually, for up to 60,000 Zaps per year, unlimited campaigns, two integrations, MFA, webhooks and logs, and insights. Annual Premium is £0 monthly, plus from 0p per Zap, billed annually, for up to 120,000 Zaps per year, unlimited campaigns and integrations, and a dedicated account manager. Annual tiers trade monthly caps for yearly quotas; Basic and Standard retain tighter campaign or integration limits than Pro and Premium.

Pay As You Go Basic has no membership fee shown and costs from 0p per Zap. It allows 500–unlimited Zaps per month, one campaign, one Zap format, a minimum send of 500 Zaps, and email and chat support. The minimum send makes it a poor match for smaller tests. Enterprise has custom pricing for large organisations.

The one-off trial campaign requires no credit card, and ZAP~POST advises testing with at least 1,000 recipients. That scale is above the Pay As You Go minimum but also consumes the full Monthly Basic allowance, so trial size and plan choice should be considered together.

Platforms

ZAP~POST is available on web and by API. The API option supports teams connecting campaigns to their own systems, while the web app provides campaign design and management.

Who it's for

ZAP~POST is best for businesses with established ecommerce, CRM, or CDP workflows that want physical mail triggered by customer activity and personalized at recipient level. It is less suitable for teams seeking a simple one-off mailing with predictable all-in pricing, or for organizations that need first-class costs fixed online before planning.

Pros and cons

• Pro: Event-triggered campaigns and one-to-one personalization connect physical mail to customer workflows rather than relying only on manual sends.
• Pro: Address validation, record cleansing, and credits for rejected records can reduce avoidable waste.
• Pro: Multiple mail formats, API connections, and named integrations support varied campaign setups.
• Con: First-class prices are not shown online, and country-level specifications, prices, and turnaround vary, complicating campaign budgeting.
• Con: Conversion attribution depends on the customer’s own analytics, adding measurement work for teams without established tracking.
• Con: The Pay As You Go option requires a minimum 500-Zap send and allows only one campaign and one format.

Alternatives

DocuPost is worth considering for a simpler pay-per-mailpiece approach: its free plan allows unlimited sends, but adds DocuPost branding to the cover letter and retains items for 90 days.

Inkit is an alternative for teams focused on signature requests and document storage, with a free tier limited to three signature requests per month, one seat, and 10GB of storage.

Postalytics may suit teams prioritizing campaign, template, and list capacity: its free plan includes unlimited campaigns, templates, and lists, but only one login and basic integrations without Salesforce or HubSpot Premium.

Sincerely offers an audit-focused starting point: its free Audit plan supports CRM or CSV import, mailability checks, brand assets, and draft editing, but cannot send mail.

Stannp is another option for teams seeking a free plan with a large contact allowance: its free tier includes 50,000 contacts and 20 virtual printer items per month for one user.

thanks.io may appeal to teams wanting pay-as-you-go mail without a monthly subscription fee; full API access is included, while gift cards require a Business, Professional, or Enterprise plan.

Lob Address Verification is the more focused alternative when the main need is address verification rather than automated mail campaigns.

PostPilot is an alternative with a free plan that charges for postcards and postage while providing access to its full platform and more than 10 analytics reports.

Verdict

Choose ZAP~POST if your business wants to trigger personalized physical mail from customer events and can connect it to an existing CRM, ecommerce, or CDP workflow. Its automation, data validation, and format choice make that use case compelling. Look elsewhere if you need published first-class pricing, fixed cross-country terms, or conversion attribution handled within the mail platform.
