Our verdict on SendLayer
SendLayer is a transactional email delivery service for websites, applications, developers, and businesses. It accepts outgoing messages through an Email API or SMTP relay, making it suitable for WordPress sites, online stores, and custom applications that need operational email rather than broad campaign marketing. The service includes delivery logs, open and click tracking, bounce and suppression management, analytics, domain authentication, and event-based webhooks. A 200-email trial is also available.
Pricing is organized around annual billing. Starter costs $5 per month and includes API or SMTP relay, suppression management, open and click tracking, bounce management, event-based webhooks, and standard support. Business costs $15 per month and adds premium support to the same listed capabilities. Growth costs $25 per month with the same feature set and premium support. Scale includes VIP support and has quote-based pricing. The verified monthly sending limit is 1,000 emails, so the service is most appropriate for lower-volume transactional workloads. The annual billing requirement also matters for buyers seeking month-to-month flexibility.
SendLayer fits a mixed technical ecosystem, with web and API access plus integrations for WordPress, WooCommerce, Magento, BigCommerce, Joomla, Drupal, Laravel, and Help Scout. Its documentation supports API and SMTP setup, while DKIM, SPF, and DMARC authentication and two-factor authentication address core account and sending controls. Event-based webhooks and detailed delivery logs are useful for applications that need delivery status and email-event handling. Choose SendLayer when API or SMTP access, commerce integrations, and operational visibility are priorities at modest volume. Consider an alternative if you need higher verified sending limits, non-annual paid billing, or a broader visual template workflow.
