What Mailrelay does
Mailrelay, operated by the privately held Spanish company CPC Servicios Informáticos Aplicados a Nuevas Tecnologías S.L. (registered in the Commercial Registry of Madrid, headquartered in Torrelodones, Madrid), is an email-marketing platform that allows businesses and individuals to create, send, and analyze marketing email campaigns. The product spans four primary modules: email marketing (contact import, segmentation, automation workflows, A/B testing, advanced analytics including open/click heatmap and inbox-placement tracking), transactional email/SMTP relay (a proprietary SMTP server with SmartHost and REST API for high-volume or application-driven sending, documented at apidocs.mailrelay.com), SMS and WhatsApp marketing (per-country credit tables, GSM-7 and Unicode encoding support), and landing pages with subscription forms. The company serves two principal segments: SMBs and individuals acquired through a self-serve freemium funnel (80,000 emails per month to 20,000 contacts permanently free), and large enterprises and high-volume senders (IKEA, Walmart, Tata Motors, Mediaset Spain, Save the Children, Aeromexico, the United Nations, SEAT, RE/MAX) reached through direct sales, custom development, dedicated IP rentals, and professional services.
The underlying technology is described as 100% proprietary and Spanish-built, with Mailrelay owning its own IP ranges and operating high-performance SMTP servers with multiple proprietary deliverability technologies that the company claims no single-server deployment can replicate. The platform exposes a REST API, integrates natively with WordPress and PrestaShop via first-party plugins, supports SMTP relay and SmartHost for transactional workloads (a Mediaset Spain case study documents up to 5 million emails per hour), and ships with an AI-powered drag-and-drop email editor for AI-generated newsletter content. Compliance posture covers GDPR, LSSI, LOPDGDD, CAN-SPAM, LGPD, and CASL, with documented Article 28 sub-processor agreements with Net Real Solutions S.L.U. (Spain) and Intergo Telecom Ltd (Cyprus/Spain) for SMS delivery.
Mailrelay's revenue model is a hybrid of (i) subscription plans billed annually with 12-month commitments — Standard at €48/month and Enterprise at €67/month, plus a permanent free tier; (ii) prepaid email-credit packages (25,000 to 10,000,000 emails) with no subscriber limit and no commitment; (iii) usage-based SMS and WhatsApp credits priced by destination country and encoding; (iv) professional services billed hourly (ESP consultancy €250/hour, email marketing strategy consultancy €150/hour, custom development and integration €300/hour, template design and panel management €100/hour, with a 50% emergency surcharge); and (v) annual recurring dedicated IP rentals (1 IP €600/year, 8 IPs €3,360/year, 32 IPs €7,680/year), with email overages at €0.01 each. Distribution is primarily self-serve product-led growth through localized mailrelay.com websites in English, Spanish, and Portuguese, supplemented by direct enterprise sales, official PrestaShop and WordPress plugins, and a content-marketing engine built around a multilingual blog and an extensive A–Z marketing glossary.

Mailrelay competitors and assessment
Company assessmentBroad incumbents
- Constant Contact: Constant Contact is an established US email and digital marketing platform aimed at small businesses and nonprofits — overlapping with Mailrelay's SMB and NGO segments (Save the Children-type customers) and offering comparable email + landing-page + automation bundles.
- SendGrid (Twilio): SendGrid, owned by Twilio, is a leading cloud email API and SMTP platform focused on transactional and high-volume marketing email at enterprise scale — broader than Mailrelay, but overlapping materially on SMTP relay, transactional email, and enterprise volume customers (Tata Motors-like profile).
Direct peers
- Moosend: Moosend is a Greece-based email marketing platform with automation, landing pages, and subscription forms at SMB-friendly pricing — directly comparable to Mailrelay's feature set and Mediterranean-European SMB target market.
- Mailjet: Mailjet (now part of Sinch) is a Paris-based transactional and marketing email API/SMTP provider with a developer-friendly offering — directly overlapping Mailrelay's SMTP/API and transactional email positioning for developers and high-volume senders.
- Klaviyo: Klaviyo is a US-based e-commerce-first email and SMS marketing platform with deep Shopify/WooCommerce integrations. Comparable to Mailrelay's PrestaShop/WordPress positioning and SMS add-on, though Klaviyo focuses exclusively on commerce use cases at premium price points.
- ActiveCampaign: ActiveCampaign offers email marketing, automation, and CRM with strong SMB/mid-market positioning — directly comparable to Mailrelay's automation workflows, segmentation, and pricing tiers. Both target businesses seeking advanced automation without enterprise complexity.
- AWeber: AWeber is a long-tenured US email marketing platform serving SMBs and solopreneurs with a freemium tier and landing pages — directly comparable to Mailrelay's SMB positioning, free tier, and landing-page builder.
- Brevo (formerly Sendinblue): Brevo is a Paris-headquartered all-in-one marketing platform combining email, SMS, CRM, and transactional messaging — directly mirroring Mailrelay's product breadth across email/SMS/landing pages/SMTP. Comparable freemium positioning and multilingual European roots make it the closest head-to-head competitor.
- GetResponse: GetResponse is a Poland-based email marketing and automation platform with landing pages, webinars, and a freemium tier — directly competing with Mailrelay for SMB and mid-market customers in Europe and Latin America.
- Mailchimp: Mailchimp is the dominant SMB email-marketing platform (now owned by Intuit) offering drag-and-drop editors, automation, and a freemium tier — directly competing with Mailrelay's core offering. It is the primary global benchmark that Mailrelay positions against (e.g., SEAT case study notes replacing Mailchimp).
