Build it by describing it

Type a sentence like this and the copilot builds, validates and simulates the workflow.
When “New Email Activity” happens in MailerSend, check the details with AI, then “Send Email” and tell my team in Slack.

Triggers

Start a workflow when this happens

    New Email Activity

    Triggers when MailerSend records new activity for the emails of a domain: sent, delivered, opened, clicked, bounced, unsubscribed, spam complaint… You can choose which event types to watch.

Actions

Then Calibra can do this for you
  • DO
    Send Email

    Sends an email through MailerSend with your own subject and HTML or plain-text content. You can add CC, BCC, a reply-to address, tags and schedule it for later.

  • DO
    Send Email with Template

    Sends an email using one of your MailerSend templates and fills in its {{variables}} with your data. The from address and subject can come from the template.

  • DO
    Send Bulk Emails

    Sends many different emails in one request through MailerSend (up to 500, or 5 on Sandbox accounts). MailerSend processes them in the background: use "Get Bulk Email Status" with the returned ID to check the result.

  • DO
    Get Bulk Email Status

    Checks how a MailerSend bulk request is going: its state, how many recipients it had, how many were suppressed and any validation errors.

  • DO
    List Recipients

    Lists the recipients MailerSend has sent emails to, optionally for one domain, one page at a time.

  • DO
    List Suppressions

    Lists the entries of one of your MailerSend suppression lists (blocklist, hard bounces, spam complaints, unsubscribes or on-hold list), one page at a time.

  • DO
    Add to Suppression List

    Adds email addresses to a MailerSend suppression list (blocklist, hard bounces, spam complaints or unsubscribes) so MailerSend stops sending to them.

  • DO
    Remove from Suppression List

    Removes email addresses (or blocklist patterns) from a MailerSend suppression list so MailerSend can send to them again. It looks up the entries by address, so you don't need their IDs.

  • DO
    List Email Activity

    Lists what happened to the emails of a MailerSend domain in a date range: sent, delivered, opened, clicked, bounced, unsubscribed, spam complaints….

  • DO
    Custom MailerSend API Request

    Makes a request to any endpoint of the MailerSend API (api.mailersend.com/v1) with your API token.
