Email

Connect your Postmark server. The emails your users get then go out through Postmark, from your own address.

Before you start, read Connect your email provider. This article covers what is specific to Postmark.

Important

Postmark only sends mail from addresses and domains that you have verified in Postmark. Verify your From address there before you connect. Postmark's sending guide is at https://postmarkapp.com/developer/api/email-api.

Who can use it

Only a workspace owner or admin can connect a provider. Only workspace owners and admins can open Email providers.

Connect Postmark

  1. Open Email providers in your workspace settings.
  2. Select Postmark under Email services.
  3. Type a short name in Name, such as Acme Notes Postmark.
  4. Type the address your users see in From address.
  5. Type your company name in From name (optional).
  6. Leave Message stream (optional) as it is, unless you created a separate stream for this mail.
  7. Paste your Postmark server API token into Server API token.
  8. Select Connect provider.
Workspace settings menu with Email providers marked 1.
Email providers page with the Postmark tile marked 2.
Connect Postmark form with each field marked by its step number, from 3 to 8.

IvaBoard saves the token securely. Afterwards the card shows at most its last 4 characters.

Check the connection and send a test email

  1. Select Check connection on your Postmark card.
  2. The result shows on the card within about a minute. If it does not, reload the page.
  3. Select Send a test email once the check has passed.
  4. Reload the page to see the result.

Postmark connection after a passed check, with Send a test email marked 3.

The test email goes to your own verified address, not to your users. When both pass, the card shows Active. Then choose Postmark for a product in its email sender settings. Connect your email provider explains how.

Note

If the card says "The provider refused the credential", select Replace credential on the card, paste a new token and check the connection again. If it says "The provider refused the From address", select Edit on the card and use an address that Postmark has verified.

Turn on bounce reports

Postmark can tell IvaBoard when an address bounces for good, or when someone marks your email as spam. You do not paste a key for Postmark. IvaBoard creates a user name and a password for the webhook instead.

  1. Select Turn on bounce reports.
  2. Select Copy next to Webhook address.
  3. Select Copy next to User name.
  4. Select Copy next to Password.
  5. Open the Webhooks settings for your message stream in Postmark.
  6. Add the webhook address as a bounce webhook.
  7. Add the same webhook address as a spam complaint webhook in the same place.
  8. Enter the User name and the Password that IvaBoard showed you in Postmark's webhook form.
Postmark connection with Turn on bounce reports marked 1.
Bounce reports on for Postmark, with the webhook address, user name and password shown once and each Copy marked 2 to 4.
Note

IvaBoard shows the webhook address, the user name and the password once. If you lose them, select New address on the card to get new ones. The old ones stop working at once.

Postmark's bounce webhook guide is at https://postmarkapp.com/developer/webhooks/bounce-webhook.

Example

For example, Sam connects Postmark for Acme Notes. Sam types Acme Notes Postmark in Name, [email protected] in From address and pastes the server API token into Server API token. Then Sam selects Connect provider and turns on bounce reports.
