Spotler Mail+ and Mailchimp: two different platforms

Spotler Mail+ and Mailchimp are both widely used email marketing platforms in the UK. Both platforms offer a drag-and-drop editor, automation, and reporting. Even so, the two platforms represent fundamentally different philosophies. Mailchimp is a US-based platform, owned by Intuit, with global scale and a large integration ecosystem. Spotler Mail+ is a European platform headquartered in The Hague, with a UK support team, serving former Pure360 customers who have now fully migrated onto the Mail+ platform.

The UK GDPR test: where does your data actually live?

For UK organisations, this is often the most consequential difference between the two platforms. The compliance landscape here has genuinely shifted since this guide was first drafted.

Important correction: the EU-UK adequacy decision did not lapse. It was extended on a technical basis through 27 December 2025, to give the European Commission time to assess the UK’s Data (Use and Access) Act 2025. On 19 December 2025, the Commission renewed the adequacy decision for a further six years, through to 27 December 2031. UK organisations can continue to rely on the adequacy framework for EU-to-UK transfers.

What has changed on schedule: key provisions of the UK’s Data (Use and Access) Act 2025 (DUAA) came into force on 5 February 2026. These provisions update requirements around lawful processing, data subject request timeframes, “recognised legitimate interests,” and international transfer tests. A further provision, the statutory right to complain directly to a data controller, comes into force on 19 June 2026.

Spotler Mail+: data is hosted on EU and UK servers via the Spotler Group. There is no US ownership, so there is no CLOUD Act exposure. The platform is ISO 27001 certified. A Data Processing Agreement is included as standard.

Mailchimp: data is held on US servers. As part of Intuit, Mailchimp is subject to the US CLOUD Act. This law means US authorities can compel access to data held by US companies regardless of where that data is physically stored. Compliance is maintained via the EU-US Data Privacy Framework. This framework’s long-term legal durability remains a live topic among privacy lawyers. A Data Processing Agreement is available but requires extra steps in the UK onboarding flow.

Organisations in regulated sectors, such as healthcare, education, and financial services, should still take specific advice on cross-border transfer mechanisms. The adequacy framework itself, however, remains in place.

Recommendations by use case

• UK ecommerce (mid-market): choose Spotler Mail+, for its integrations with Shopify, WooCommerce, Magento, Lightspeed, and Shopware.
• B2B with considered sales cycles: choose Spotler Mail+, for CRM alignment and UK GDPR-compliant data processing.
• Charities and public sector: choose Spotler Mail+, with a track record among NHS trusts and UK charities, UK support, and a Data Processing Agreement included.
• Start-ups and small teams: choose Mailchimp. The platform is free for up to 250 contacts (reduced from 500 as of February 2026), has the most intuitive editor, and offers the largest template library.

Pricing and value

Spotler Mail+: Spotler publishes pricing per product at spotler.com/en-gb/pricing. Mail+ Professional starts from £81 per month, with 1,000 emails per year included. Mail+ Automation starts from £288 per month and Mail+ Ecommerce from £306 per month, each with 5,000 emails per year included. Prices exclude VAT. Every plan runs on a 12-month contract, and you can pay monthly, quarterly, or annually. The pricing page also includes a configurator: you pick the products and volume you need and see an indicative total monthly price straight away. For higher email volume, multiple products, or custom requirements, you then request an additional quote.

Mailchimp: pricing is fully published by tier. There is an important catch: Mailchimp bills for unsubscribed and inactive contacts unless you manually archive them. This can meaningfully inflate the effective monthly cost for lists with natural churn. As of February 2026, the free plan has been reduced to 250 contacts and 500 emails per month, with a 250 email daily send cap. Previously, the free plan offered 500 contacts and 1,000 emails per month.

Tip: before comparing Mailchimp’s list price to a Mail+ quote, check how many of your contacts Mailchimp actually classifies as billable.

Conclusion

Spotler Mail+ is a strong choice for UK organisations where UK GDPR compliance, data residency, and local support are priorities. The platform also stands out for its segmentation depth, strong integrations with UK ecommerce platforms, and a pricing page where you can configure a package yourself and see an indicative price straight away. For higher email volume or custom requirements, you simply request an additional quote.

Mailchimp is a good option for small teams, start-ups, and international brands where data location is less of a deciding factor. The platform is strong thanks to its user-friendly editor, extensive template library, and broad integration ecosystem. Its free tier, however, has become considerably more limited since 2026.
