Claude for email marketing connects through your email platform: Klaviyo, Mailchimp, Customer.io, ActiveCampaign, HubSpot, Kit, MailerLite and Constant Contact all have connectors. Most can report, build segments and create campaigns, and several can send. Use Claude to analyse, draft and build. Keep sending, unsubscribes and deletions on Needs approval, because none of them can be undone.
This is part of our series on Claude connectors for marketing, role by role. Set up the ten connectors every team needs first; this kit sits on top.
What does Claude do for an email marketer?
Lifecycle work is mostly the same four jobs on repeat: see what worked, decide who gets what, build the next email or flow, and keep the list clean. We call the connectors for them Intersect's Marketing Kit for email and lifecycle.
Intersect's Marketing Kit: email and lifecycle
| # | The job | Connector | What Claude can do | Start it on |
|---|---|---|---|---|
| 1 | E-commerce email and SMS |  Klaviyo | Flows, campaigns, segments and revenue by message. | Needs approval |
| 2 | Small-business email |  Mailchimp Constant Contact MailerLite | From a goal or a description to a designed campaign. | Needs approval |
| 3 | Creators and newsletters |  Kit | Broadcasts, sequences, tags and subscriber growth. | Needs approval |
| 4 | Lifecycle and automation |  Customer.io ActiveCampaign Brevo | Journeys, segments, deliverability, A/B results. | Needs approval |
| 5 | Email inside the CRM |  HubSpot | Which emails reached people who went on to buy. | Needs approval |
| 6 | Design and brand |  Migma | On-brand emails that render everywhere, with deliverability checks. | Creates drafts |

The connectors, one at a time
Ten platforms. You'll use the one you already pay for, so read that section and skim the rest. Most of them can send, so start each on Needs approval. Brevo is the exception: its connector never sends or deletes.
1. Klaviyo: e-commerce email and SMS
Klaviyo's connector reads campaigns, flows, lists, segments, metrics, events and catalogue items, creates campaigns, assigns templates, uploads images and manages profiles and subscriptions. For e-commerce brands it's the one to start with.
What you can do with it
- Find which flows made the most revenue, and where people drop out of them.
- Draft a campaign around this week's best-selling products from the catalogue.
- Compare open and click rates by segment over the last six months.
Try: “Which flows made the most revenue last month, and which have the biggest drop between email two and three?”
2. Mailchimp: from goal to campaign
Mailchimp's connector starts from a business goal and produces a campaign plan with designed layouts, not just copy. Claude can edit the text, swap images, apply your theme, generate images and pull product images from your site, then save it all to your Mailchimp account.
What you can do with it
- Turn “clear winter stock before January” into a three-email plan with layouts.
- Restyle an existing campaign in your brand theme.
- Pull product images straight from your site into the email.
Try: “Plan a three-email campaign to clear our winter stock before January, using product images from our site, and save it to Mailchimp as a draft.”
3. Customer.io: lifecycle automations
Customer.io's connector builds and edits campaigns, broadcasts and newsletters, analyses deliveries, opens, clicks and conversions, diagnoses deliverability and manages data pipelines. Read, write and delete access are granted separately, per workspace, so you can allow reading and building without ever allowing deletes.
What you can do with it
- Diagnose why one campaign's open rate fell off a cliff.
- Build an onboarding journey from a plain-English description.
- Create a segment such as “trial users who haven't invited a teammate”.
Try: “Our activation emails' open rate dropped last week. Check deliverability, compare with the previous month and tell me what changed.”
4. ActiveCampaign: email, automations and pipeline
ActiveCampaign's connector has more than 390 tools covering campaigns, automations, contacts, tags, lists, deals and reporting. Claude can review past campaigns and customer activity, audit automations, check audience health and build the next campaign in your account.
What you can do with it
- Audit every automation for broken steps or contacts stuck in limbo.
- Check list health: bounces, inactive contacts, missing tags.
- Build and send a campaign to a tagged segment, after approval.
Try: “Audit our automations: which haven't sent anything in 60 days, and which have contacts stuck at one step?”
5. HubSpot: email inside the CRM
If your email sits in HubSpot, its connector reports on marketing emails and campaign attribution, manages emails and segments, and works with the contacts behind them. A lifecycle question and a pipeline question become the same conversation.
What you can do with it
- See which nurture emails were opened by contacts who later became customers.
- Build a segment from CRM properties for the next send.
- Compare email performance by lifecycle stage.
Try: “Which marketing emails last quarter were most often opened by contacts who went on to close? Build a segment of similar contacts who haven't bought yet.”
6. Kit: creators and newsletters
Kit (formerly ConvertKit) is built for creators and newsletter businesses. Its connector answers questions about your subscribers, broadcasts and performance, then acts: tagging subscribers, managing segments, drafting and scheduling broadcasts, enrolling people in sequences, and creating landing pages and products. It has more than 80 tools.
What you can do with it
- See which broadcasts gained subscribers and which lost them.
- Tag everyone who clicked a link about a topic, for a later sequence.
- Draft and schedule next week's broadcast.
Try: “Which of the last ten broadcasts had the most unsubscribes, and what did they have in common?”
7. MailerLite: a straightforward email assistant
MailerLite's connector builds emails, schedules and cancels campaigns, reports on performance and manages subscribers and groups, including a subscriber's activity. It suits small teams that want the basics done well.
What you can do with it
- Compare the last six campaigns' opens and clicks.
- Move subscribers between groups based on what they clicked.
- Draft and schedule a campaign to one group.
Try: “How did the last six campaigns perform, and which group engages least?”
8. Constant Contact: describe it, preview it
Constant Contact's connector generates the email's HTML from a description and shows a live preview in the conversation. You ask for changes, preview again, and when it's right it's imported into your Constant Contact account. It also scores subject lines and checks whether a campaign is ready to schedule.
What you can do with it
- Describe an event invitation and get a designed email back.
- Score three subject lines before you choose.
- Check a campaign is ready to send: sender, address, list.
Try: “Make an invitation for our customer evening on 4 December, with an RSVP button, and score three subject lines for it.”
9. Migma: on-brand emails that render everywhere
Migma reads your website and builds a brand profile (logo, colours, fonts, tone), learns from past emails it can import from Klaviyo, Mailchimp or HubSpot, and writes campaigns, welcome series and transactional emails in the same style. Previews show in the conversation, with a visual editor for hand changes, plus deliverability and consent checks. It renders across inboxes from Gmail to Outlook 2003.
What you can do with it
- Rebuild your welcome series in your brand without a designer.
- Check an email renders in old Outlook before it goes.
- Get segment suggestions from a plain description of who you want to reach.
Try: “Using our brand, write a three-email welcome series for new trial users and show me previews.”
10. Brevo: drafts only, by design
Brevo's connector analyses campaign performance and A/B test results, looks up contacts, explores segments and drafts HTML templates, email campaigns and SMS campaigns into your Brevo account. It never sends or schedules a campaign and never deletes anything, so it's a safe one to hand to a whole team. It works on every Brevo plan.
What you can do with it
- Read last month's A/B tests and say which differences mattered.
- Draft an email and an SMS for the same promotion.
- Look up a contact's history before replying to a complaint.
Try: “Which of last quarter's A/B tests produced a meaningful difference, and what should we test next?”
What should an email team connect first?
Your email platform, read only, for a week. Ask it the questions you normally answer with exports. Then switch on drafting and building, and leave sending for last.
Where does this break?
- A send can't be undone. Keep sending on Needs approval, and send a test to yourself first.
- Consent matters. Subscribe and unsubscribe tools change who can legally be emailed. Treat them as carefully as sends.
- Customer data enters the chat. Profiles hold personal information. Ask for aggregates unless you need an individual.
- Delete means delete. Where a connector can delete, as Customer.io can when you grant it, leave that switched off.
Want your lifecycle programme built faster, and sent carefully?
We'll connect your email platform, set what Claude may build and what must wait for approval, and set up the weekly report your team reads.
