Definition
What Is the SyncMate + Mailchimp Integration?
The SyncMate + Mailchimp integration adds WhatsApp as a channel alongside your email campaigns. When a contact joins an audience, gains a tag or ignores a campaign, SyncMate sends a WhatsApp message from your own number — without the WhatsApp Business API or BSP approval.
What is Mailchimp?
Mailchimp is an email marketing platform for managing audiences, tags, campaigns and automated Customer Journeys — no developer needed.
SyncMate reaches Mailchimp over a webhook, so this is no-code automation end to end. You can run it on your existing number with no Meta verification, or connect the official WhatsApp Business API when you need a verified business identity — both are supported.
Setup
How to Connect WhatsApp to Mailchimp
Five steps, under five minutes, no code at any point.
1
Step 1 — Create Your Free SyncMate Account
Sign up at app.assistro.co. The free plan includes 450 messages a month, so you can test the whole workflow before paying for anything.
2
Step 2 — Link Your WhatsApp Number
Scan a QR code to connect your personal or WhatsApp Business number, or connect the official Meta Business API if you need the verified badge. No BSP required either way.
3
Step 3 — Connect Mailchimp to SyncMate
Authorise Mailchimp in SyncMate and choose the audience, tags and campaign events the integration should watch.
4
Step 4 — Map Your Trigger and Message Fields
Pick the trigger — campaign sent and not opened after 24 hours — then map first name, campaign title and a link into the WhatsApp follow-up.
5
Step 5 — Test and Publish
Run a test send, check it arrives on the right number, then switch the automation on. Every send is logged, so a failure surfaces instead of disappearing.

Capabilities
Everything You Can Do with SyncMate for Mailchimp
Twelve capabilities, unlocking Mailchimp WhatsApp automation across your whole stack.
Non-Opener Follow-Up
Reach the people email missed, without resending the email.
Tag-Based Sends
A tag change sends the message written for that segment.
Audience Welcomes
A WhatsApp welcome the moment a subscriber joins a list.
Journeys as a Channel
Use WhatsApp as a step inside a Customer Journey.
Scheduled Delivery
Hold a message until the moment it will actually land — by delay or by clock.
File Sharing
Send PDFs, images and invoices as part of an automated workflow.
Smart Filtering
Only send when your conditions are met, so nobody gets messaged twice.
Data Mapping
Drop any field from the trigger record straight into the message body.
Dynamic Templates
One template, variable data — every message reads as if written once.
Notification Chains
Sequence timed follow-ups that stop the moment somebody replies.
Secure Transfers
Messages move over encrypted channels. Assistro never sells conversation data.
Performance Tracking
Delivery and read status logged on every send, exportable for review.
Reach the People Email Missed
A campaign that gets a 30% open rate leaves most of the list untouched. A WhatsApp follow-up to the non-openers reaches them on a channel they check.
Non-openers: follow up automatically after a set delay
Segments: different message per tag or audience
Conditions: only message the contacts who qualify

Consent, Handled Properly
An email opt-in is not a WhatsApp opt-in. SyncMate is built to respect that, and the integration is designed around collecting channel consent rather than assuming it.
Record WhatsApp consent as a Mailchimp field or tag
Only send to contacts carrying that consent flag
Use cases
Real Use Cases for WhatsApp + Mailchimp Automation
Named, concrete workflows — not abstractions. Each one is a few minutes of setup.
Marketing: Non-Opener Re-Engagement
A 30% open rate leaves most of your list untouched. WhatsApp reaches the rest.
Example workflow
Campaign not opened after 24h → WhatsApp follow-up with the headline
Marketing: Subscriber Onboarding
Welcome people on both channels so the first impression is not sitting in spam.
Example workflow
Contact added to audience → WhatsApp welcome alongside the email
Marketing: Segment-Triggered Offers
Let the tag do the targeting, and send only to contacts who opted in on the channel.
Example workflow
Tag “VIP” applied → WhatsApp early-access offer
Shopify integration
Retention: Win-Back Sequences
Lapsed contacts respond better to a short message than another newsletter.
Example workflow
Journey step reached → WhatsApp win-back message
WooCommerce integration

Comparison
SyncMate vs. the Official WhatsApp Business API
SyncMate supports both routes. Run it on your existing personal or WhatsApp Business number, or connect through the official Meta WhatsApp Business API — same integration, two connection paths, switchable later. Here is what actually differs.

BSP (Business Solution Provider) is a Meta-approved partner that resells access to the official WhatsApp Business API. Going that route normally means business verification, template pre-approval and per-conversation pricing. SyncMate can run either way — through a BSP-free personal number, or through the official API when you need the verified badge.

FAQs
WhatsApp + Mailchimp Integration FAQs
Can I use Mailchimp to send WhatsApp messages?
Yes. SyncMate's Mailchimp integration sends automated WhatsApp messages triggered by Mailchimp events like audience joins, tag changes and campaign activity.
Do I need the WhatsApp Business API to use Mailchimp with WhatsApp?
No. SyncMate connects your personal or WhatsApp Business number directly, with no Meta verification and no BSP (Business Solution Provider) approval. If you do want the official API and the green verified badge, SyncMate supports that too — it is a connection setting, not a different product.
How do I connect WhatsApp to Mailchimp with SyncMate?
Create a free SyncMate account, link your WhatsApp number by scanning a QR code, then authorise Mailchimp in SyncMate and pick the audience and tags to watch. Map your message fields, send a test, and publish.
How much does the WhatsApp Mailchimp integration cost?
SyncMate has a free plan with 450 messages per month. Paid plans start at $5/month (Personal), then $12/month (Professional) and $30/month (Business) for higher volumes and larger media limits.
Is coding required to connect WhatsApp to Mailchimp?
No coding is required. Both Mailchimp and SyncMate are no-code platforms — you build the automation through a visual interface.
What can I automate with WhatsApp and Mailchimp?
Common automations include subscriber welcomes, non-opener follow-ups, segment offers triggered by a tag, and win-back messages inside a Customer Journey.
Do I need separate consent to message Mailchimp contacts on WhatsApp?
Yes. An email subscription is not permission to message someone on WhatsApp. Collect and record channel consent separately — SyncMate can filter on a Mailchimp tag or field so only opted-in contacts are messaged.
Can I send WhatsApp messages with attachments through Mailchimp?
Yes. SyncMate sends documents, images and files — PDF, PNG, JPG and more — inside automated workflows. Media size limits vary by plan.
