Email infrastructure built for developers, marketers & AI agents
Send transactional emails, marketing campaigns, and automated sequences at scale. One API to manage your transactional emails, campaigns, automations, and contacts, also featuring an MCP server for AI agents.
For solopreneurs, Sendkit enables sending both essential transactional emails like invoices and marketing newsletters to clients. For example, a freelance designer can use Sendkit to automatically send a PDF invoice after completing a project and also send a monthly newsletter showcasing new work to their client list.
For small business owners, Sendkit enables the automation of customer onboarding sequences to improve engagement and retention. For instance, a local gym owner can use Sendkit to automatically send a welcome email with class schedules, followed by a series of tips and offers over the first week of a new member's subscription.
For e-commerce store owners, Sendkit enables efficient management of order confirmations and targeted promotional campaigns. For example, an online boutique can use Sendkit to send immediate order confirmation emails with tracking details and then later send segmented promotional emails for new arrivals to customers who have previously purchased similar items.
For SaaS companies, Sendkit enables sending critical transactional emails like password resets and feature update announcements to users. For instance, a software-as-a-service provider can use Sendkit to send an automated email when a user requests a password reset and also broadcast a campaign announcing a new feature with a link to a tutorial.
Sendkit offers a free tier that includes 3,000 transactional emails per month with one sending domain. No credit card is required to start, and you can upgrade to a paid plan when you need more volume.
Sendkit's pricing is based on email volume, not the number of contacts. Plans start at $15.00/month for the Transactional plan and $30.00/month for the Marketing plan, with overage charged at $1.00 per 1,000 emails.
Alternatives to Sendkit include Mailchimp (though transactional email is an add-on), SendGrid (separate billing for transactional/marketing, contact-based pricing), and Amazon SES (raw infrastructure with no dashboard or built-in features).
Yes, Sendkit ensures data security by encrypting all data in transit (TLS) and at rest (AES-256). They adhere to industry best practices and are compliant with GDPR and LGPD data protection regulations.
Sendkit offers a unified platform for transactional and marketing emails with pricing based on volume, while SendGrid uses separate products for each, employs contact-based pricing, and has been known to freeze accounts.
Sendkit is primarily a web-based service accessible through a browser, and there is no mention of dedicated mobile applications for iOS or Android on their website.
Sendkit does not require a traditional installation as it is a cloud-based service. You can integrate it into your applications using their RESTful Sending API or SMTP relay.
We're still verifying the official pricing for Sendkit. In the meantime, the most up-to-date plans and prices are available directly on the publisher's website.
