Frequently asked

Connecting email

How do I send email from my app or platform?

Most platforms accept an SMTP relay: set the SMTP host, port, username, and password in your app's email settings. MailKite's SMTP endpoint is smtp.mailkite.dev (port 587 with STARTTLS or 465 with TLS), username 'mailkite', and your API key as the password. Frameworks like Laravel, Django, and Rails have first-class SMTP drivers; CMS platforms like WordPress use an SMTP plugin.

Which platforms accept inbound email?

Helpdesk tools (Zendesk, Freshdesk, Help Scout) turn inbound email into tickets. Project tools (Jira, Linear, Asana, Trello) accept email to create issues or cards. Chat tools (Slack, Teams) can post emails to channels. MailKite routes inbound email to these platforms over IMAP or via webhook with a parsed JSON payload.

Do I need a separate email service for transactional and marketing?

It's common to pair them: a transactional service (MailKite, Resend, Postmark) for receipts and alerts, and a marketing platform (Mailchimp, Klaviyo, HubSpot) for campaigns. MailKite handles both inbound and transactional outbound from one API, so you can consolidate over time.

Can I keep my existing email provider and just add inbound?

Yes. Many teams start by moving only inbound email to MailKite (point MX at MailKite, receive parsed JSON webhooks) while keeping their existing outbound provider. You can consolidate sending onto MailKite later since send and receive share one quota.

Point a domain. Connect everything.

One SMTP endpoint, one API, one quota for send + receive. Unlimited domains, no credit card.
