Mailchimp and Conduyt

Send newsletters from Mailchimp and sell from Conduyt without exporting lists. Pick a Conduyt smart list or tag and one Mailchimp audience, and Conduyt adds and updates those contacts in Mailchimp with their name and tags. New Mailchimp subscribers come back as Conduyt contacts, and when someone unsubscribes or their address bounces, Conduyt opts them out of email so your team stops emailing them too.

How it works

What makes it different

01

Choose who goes to Mailchimp

Pick one Conduyt smart list or one tag. Its contacts with an email address and email opt-in are added to your Mailchimp audience. Contacts who have opted out of email in Conduyt, or are marked do not contact, are never sent.

02

Added or updated, never duplicated

Mailchimp keys each member by email address. Conduyt adds the member or updates the existing one with first name, last name and Conduyt tags. Changes go out within about two minutes, and a first backfill runs in batches after you connect.

03

Subscribed or pending, your choice

New people are added to the audience as Subscribed, the default, or as Pending, in which case Mailchimp sends them a confirmation email first.

04

New subscribers come back

When someone subscribes to the audience in Mailchimp, for example through a Mailchimp signup form, Conduyt creates the contact or matches it by email address, with email opt-in on and a timeline entry. First and last name changes and email-address changes made in Mailchimp update the Conduyt contact too.

05

Unsubscribes and bounces come back

With the setting on (the default), an unsubscribe in Mailchimp opts the contact out of Conduyt email, which also stops their sequences, and an address Mailchimp cleans after a bounce is opted out the same way, with a timeline entry. Conduyt never opts anyone back in because of an unsubscribe or bounce.

Before you start

What you need in place first

✓
A Mailchimp account and audienceYou sign in to Mailchimp from Conduyt and allow access. There is no API key to copy. Each connection uses one audience.
✓
Permission to email the people you syncOnly send contacts to Mailchimp who agreed to hear from you. Conduyt leaves out anyone already opted out of email, but it cannot decide consent for you.
✓
A Conduyt owner or adminConnecting Mailchimp is done in Settings, Integrations, Mailchimp by a workspace owner or admin.

Honest limits

What it does not do

✕
One audience per connectionEach connection syncs one Conduyt smart list or tag to one Mailchimp audience.
✕
Tags go one wayTags go from Conduyt to Mailchimp only. From Mailchimp, Conduyt takes new subscribers, name changes and email-address changes; other Mailchimp fields stay in Mailchimp.
✕
No campaign or segment syncMailchimp campaigns, segments, opens and clicks stay in Mailchimp.
✕
Email consent onlyText message consent is not part of this connection.
✕
Contacts without an email are skippedMailchimp members are keyed by email address, so contacts with only a phone number are not sent.
✕
Mailchimp's own limits applyIf your Mailchimp plan's contact limit blocks new members, the connection card says so in plain words instead of dropping them silently. They are retried when you save the settings or press Push now.

FAQ

Common questions

Does Conduyt integrate with Mailchimp?

Yes. Conduyt keeps one Mailchimp audience in step with a Conduyt smart list or tag, sending email, first name, last name and tags. New Mailchimp subscribers come back as Conduyt contacts, and unsubscribes and bounced addresses come back so those contacts are opted out of email in Conduyt.

Do people who sign up through Mailchimp appear in Conduyt?

Yes. Anyone who subscribes to the connected audience in Mailchimp is created as a Conduyt contact, or matched to an existing one by email address, with email opt-in on and a timeline entry. That includes people who never came from your smart list or tag.

If someone unsubscribes in Mailchimp, will Conduyt stop emailing them?

Yes. An unsubscribe in Mailchimp opts the contact out of Conduyt email, which also stops their sequences. It usually arrives right away through the webhook, and within 15 minutes at the latest through the status check.

Will contacts be duplicated in Mailchimp?

No. Mailchimp keys members by email address, and Conduyt adds or updates the member for that address.

Do I need Mailchimp if I use Conduyt?

Not to send email. Conduyt sends automated sequences and bulk email itself. The Mailchimp connection is for teams that already run newsletters in Mailchimp and want their CRM to stay in step.

What happens if I disconnect?

Both directions stop, Conduyt removes its webhook from the audience (the card shows Disconnecting until Mailchimp confirms) and the connection is deleted in Conduyt. Nothing is deleted, archived or unsubscribed in Mailchimp.
