What It Is

SendLayer is an email delivery service for websites, brands, and applications, with a primary focus on sending transactional emails and improving deliverability. Its website highlights modern sending infrastructure and domain verification to help improve inbox placement. It supports integration via API or SMTP relay, and provides features such as email logs, analytics, bounce handling, and suppression lists.

Core Capabilities

In terms of channels, SendLayer appears to be an email-only service; there is no indication of SMS, voice, or IM capabilities. Its email features include DKIM, SPF, and DMARC authentication, open and click tracking, Bounce Management, Suppression Management, Blocklist Management, and Active Anti-Spam. For integrations, it supports API, SMTP relay, and event Webhooks, and claims seamless compatibility with 1000+ platforms. Its documentation also covers domain authorization, SMTP connections, email logs, API usage, and an error library. In terms of regional coverage, it only states that customers come from 150+ countries, without disclosing specific sending nodes or regional compliance boundaries.

Pricing

Pricing is based on annual subscriptions in USD. Starter is $5/month and includes 1,000 emails/month, 1 sending domain, and 3 days of log retention. Business is $15/month and includes 5,000 emails/month, 3 domains, and 15 days of logs. Growth is $25/month and includes 10,000 emails/month, 5 domains, and 30 days of logs.

Overage pricing is not disclosed on the website.

Pros, Cons, and Best Fit

The main advantages are its low entry price, support for both SMTP and API integration, and a relatively complete set of email authentication and deliverability management features. It is well suited to transactional email scenarios such as WordPress websites, SaaS products, order notifications, password resets, and signup verification. The limitations are that all paid plans are billed annually, lower-tier plans have short log retention, and the public materials do not provide quantified deliverability rates, latency figures, SLA terms, overage pricing, or payment method details. For highly regulated environments or large-scale enterprise email systems, it is still advisable to request a quote and run tests first.

China Access

The website does not provide information about accessibility from mainland China, RMB payments, or local support, so china_access is rated as unknown. If deploying from mainland China, it is recommended to test access to the dashboard, SMTP/API connectivity, and the DNS verification process first. Alternatives to compare include Alibaba Cloud DirectMail, Tencent Cloud Email, and overseas options such as Amazon SES, SendGrid, Mailgun, and Postmark.
