This integration lets you push your Mailkick email HTML to SendGrid Dynamic Templates.

​
Prerequisites

  • You must be a workspace admin.
  • You need a SendGrid API key with Mail Send and Template Engine permissions.

​
Step 1 — Create your SendGrid API key

  1. Log in to SendGrid
  2. Go to Settings → API Keys
  3. Click Create API Key
  4. Select Restricted Access and enable:
    • Mail Send → Full Access
    • Template Engine → Full Access
  5. Copy the generated key
Save your API key immediately — SendGrid only shows it once!

​
Step 2 — Add SendGrid in Mailkick

  1. Open Settings → Integrations
  2. Select SendGrid
  3. Paste your API key
  4. Click Save changes
Mailkick SendGrid integration settings

​
Step 3 — Sync an email

  1. Open an email in the editor
  2. Click Export
  3. Click Sync to SendGrid
After a successful sync, you’ll get a SendGrid editor link like:
  • https://mc.sendgrid.com/dynamic-templates/{template_id}/version/{version_id}/editor

​
How sync works

When you sync an email to SendGrid:
  1. First sync → Creates a new Dynamic Template with a version
  2. Subsequent syncs → Updates the existing version (idempotent via content hash)
  3. Template deleted on SendGrid → Mailkick automatically recreates it
Mailkick uses content hashing to avoid unnecessary API calls. If the HTML hasn’t changed, no update is sent.

​
Using Dynamic Templates

SendGrid Dynamic Templates support Handlebars variables. In your email, you can use:
These variables will be resolved when you send via SendGrid’s API.
