Mailchimp + Sendy

Mailchimp · Sendy

Sync Mailchimp unsubscribes to Sendy

Unsubscribe an address from a Sendy list when it unsubscribes from your Mailchimp audience. Connect both accounts, choose the Mailchimp audience and enter the same Sendy List ID used by your subscriber-sync workflow. Email is mapped automatically. Only unsubscribe events received after activation are processed; historical opt-outs are not imported. This is one-way synchronization: it does not unsubscribe people in Mailchimp, delete contacts, or process cleaned, profile-update or email-change events. If an address is absent from the selected Sendy list, Sendy can return a subscriber-not-found error; the workflow does not create a subscriber. No campaign is sent. Disable any Sendy unsubscribe notification or automation for tests without emails. The sample is fictional.

Add new Mailchimp subscribers to Sendy

Add subscribers to a Sendy list when they subscribe to your Mailchimp audience. Connect both accounts, choose the Mailchimp audience and enter the destination Sendy List ID. Email and first name (when present) are mapped automatically. Only events received after activation are processed; existing contacts are not imported. A later Mailchimp resubscription can subscribe the same address again. This is one-way synchronization; use the companion unsubscribe template with the same audience and Sendy list to propagate opt-outs. Sendy double opt-in is respected by default; this template does not assert GDPR consent or send campaigns. Sendy may send confirmation or welcome emails according to the destination list settings. For a test without emails, use a dedicated single-opt-in list with welcome emails and automations disabled. The sample is fictional.

Mailchimp + Slack

Mailchimp · Slack

Notify Slack about new Mailchimp subscribers

Send a Slack channel notification when Mailchimp reports a new subscriber for a selected audience. Connect Mailchimp and Slack, choose the audience with the standard Audiences browser, and select the destination channel. Each message contains the subscriber email address, audience ID, event type and the fired_at value supplied by Mailchimp. The source timestamp is preserved as text because the webhook does not include a timezone. The template has its own fictional Hamburg subscriber example with German characters in unused merge fields. Names, interests, signup IPs, tags and other merge fields are not copied. Subscriber email addresses become visible to members of the selected Slack channel, so use a channel with appropriate access. Wait for Connected before creating a fictional test subscriber. Existing contacts are not backfilled. Mailchimp can emit another subscribe event for a resubscription, and FastHook treats it as a separate notification. Unsubscribe, cleaned, profile-update and email-change events are excluded. The workflow does not create contacts, change marketing consent or send campaigns. Messages are plain text with link and media previews disabled. Manual reruns can post duplicate notifications.

Mailchimp + Google Sheets

Mailchimp · Google Sheets

Log new Mailchimp subscribers in Google Sheets

Append a Google Sheets row when Mailchimp sends a subscribe event for a selected audience. Keep a subscription-event register with Email, Audience ID, Event fired time and Event type in columns A-D. Connect Mailchimp and Google Sheets, choose the audience using the standard Audiences browser and browse to the destination spreadsheet and worksheet. Append Values works with an empty worksheet; headers are optional. Source fired_at text is preserved exactly without assigning a timezone that is absent from the webhook. Includes its own fictional Hamburg subscriber example with German characters in unused merge fields. Only email and subscription-event metadata are copied; names, interests, signup IPs and other merge fields are excluded. Use a sheet whose access is appropriate for subscriber email addresses. RAW input prevents formula-looking source strings from being interpreted as formulas. Wait for Connected before creating a test subscription. New subscribe events can include resubscriptions, so separate legitimate events for one address can create multiple rows. Existing contacts are not backfilled. Unsubscribe, cleaned, email-change and profile events do not update or remove past rows: this is not a current eligible-recipient list or marketing-consent record. No campaigns or messages are sent and no new audience membership is created by this template. Manual reruns can duplicate rows.
