What is Email Sequence Studio for?
An email sequence is a series of emails sent automatically, a few days apart, after an action: a newsletter sign-up, an abandoned cart, the start of a free trial… Well written, it works for you day and night.
The tool helps you write each email (subject, preheader, body, button, delay), gives you a score on 6 axes with points to improve, checks that your emails won't land in spam, then prepares files for Mailchimp, Brevo, Kit (ConvertKit) or Klaviyo.

The steps, one by one
Choose the type of sequence
Welcome, nurture, launch, abandoned cart, re-engagement, onboarding, upsell, webinar, lead magnet, review request, win-back or free trial. Enter the goal, the number of emails and the sending pace.
Describe your offer and your ideal customer
The product name, the promise, the price, the guarantee and the link to send your readers to. Then your customer: their pain points, desires and objections. This information mainly helps the AI write emails that really speak to them.
Choose your tone
Friendly, professional, direct, storytelling… formal or informal, signature, words to avoid. You can paste samples of your own writing so the AI imitates your style.
Write (or adjust) each email
Click "✏️ Edit": subject, preheader (the short text shown after the subject in the inbox), body, button and send delay in days.
Words in brackets [like this] are to be replaced with your real information. {{first_name}} will be replaced by each subscriber's first name,
and {{signature}} by your signature.
Check, then export
Look at the preview (desktop and mobile), the score and the Deliverability tab. Fill in section 8 (company, address, sender): it's mandatory for sending commercial emails. All that's left is to export to your email tool.
The score on 6 axes
The score out of 100 is the average of 6 axes: subject (length, personalisation, all subjects different), body (length, paragraphs, personalisation), CTA (a short 2-to-5-word button with a link), personalisation, timing (time, days, number of emails) and deliverability (unsubscribe, address, privacy, no CAPITALS). The "Analysis" tab tells you what to improve first.

AI (optional) (Pro)
- Full sequence: all the emails written from your offer and your ideal customer.
- 5 alternative subjects and improve a subject: pick the one you like and it replaces the selected email's subject.
- Rewrite the email in another tone, add personalisation to the whole sequence, analyse the strategy.
- Chat: ask your questions; the AI already knows your offer and your sequence.
- Open the ✨ AI tab and choose your provider: Agnes, OpenAI (ChatGPT), Anthropic (Claude), Mistral, Groq, Google Gemini, DeepSeek, OpenRouter or any OpenAI-compatible service.
- Create an API key with that provider (the link appears under the list; several offer free access, such as Agnes, Groq or Gemini).
- Paste your key, click "🔌 Test connection" then "💾 Save".
Exporting to your email tool
Email tools can't import an automated sequence from a file. So each export gives you, email by email, the subject, the preheader, the delay and the HTML code ready to paste into your tool ("HTML code" or "custom HTML" block).
- Mailchimp, Brevo, Kit (ConvertKit), Klaviyo: personalisation is converted to each tool's format (for example
*|FNAME|*for Mailchimp,{{ contact.FIRSTNAME }}for Brevo) with the right unsubscribe link. - HTML and ZIP: one file per email, mobile- and dark-mode-friendly.
- Markdown, CSV, PDF: to review, get approval or present the sequence to a client.
Where are my sequences saved?
Your sequences are saved in your browser, not on our servers. Our servers only calculate the score and prepare the exports, without keeping anything. The "🕐 History" button keeps the last 20 versions.
Discovery or Pro?
The discovery version gives you the whole tool and all its exports; exported documents (HTML, PDF, Markdown, pictures) carry a small “Made with Yok-Kod” line, data files (CSV, JSON, ICS) never do. Pro removes that line and adds AI, the 12 templates and up to 50 sequences.
| Discovery (free) | Pro | |
|---|---|---|
| Form, email editor, preview, score, analysis, deliverability, A/B testing | ✓ | ✓ |
| Library of 200 subject lines | ✓ | ✓ |
| Exports (HTML, Mailchimp, Brevo, Kit, Klaviyo, CSV, Markdown, PDF, ZIP), JSON import and export | ✓ with a “Made with Yok-Kod” line | ✓ no line |
| Templates | Welcome | All 12 |
| Saved sequences | Just 1 | Up to 50 |
| AI with your key (Agnes, OpenAI, Claude, Mistral, Groq, Gemini…) | — | ✓ |
Pro for Email Sequence Studio costs €19 as a one-off payment. It is also included in the Marketing Pack (€129) and in Full Access (€179).
Common issues
- Why isn't the score updating?
- It updates a moment after each change. If it stays frozen, check your Internet connection and reload the page.
- Why do my emails land in spam?
- Check the Deliverability tab, avoid words like "free", "urgent" or "cash" in subjects, and set up your domain authentication (SPF, DKIM, DMARC) in your email tool.
- Why doesn't the first name show in my email tool?
- Use the export designed for your tool: the merge tags are converted to the right format. Also check that the first name is filled in in your contact list.
- Why does the AI say "invalid key"?
- Check that the selected provider matches your key, then test it again. Free keys are limited to a few requests per minute.
- Why can't I find my sequence any more?
- Make sure you're using the same computer, the same browser and the same account.
