Hi. I am new to automations with Brevo and I am trying to understand how this works. Here’s my situation.

1. I have various products for sale on my website.
2. Each product has the offer of a specific promotion so I’m using different forms for each.
3. Every visitor who opts-in to this form will recieive a promotion code. (If they don’t opt-in or don’t want/already have the promotion code, they can click to be directed to the sales page.)
4. At this point, I want a condition for new contacts and pre-existing contacts.  
4.1 When new contacts opt-in, after receiving this particular product’s promo code email, I want them to receive my welcome sequence.  
4.2 For pre-existing contacts who’ve received this particular product’s promo code email, I don’t want them to receive my welcome sequence (because they’ve gotten it already through some other form). I want them to receive a different sequence of follow-ups, etc.

This may be a very basic question, but can you please help me understand how to do this. The main thing is I want new contacts to get the welcome sequence. And I don’t want pre-existing contacts to get it repeatedly.

I think I can send new ones to the welcome sequence, and keep old ones in another … But I’m sure of how to use the If/Else conditions to do this.

Hi Goodsight!  
To set this up, here’s what I’d suggest:

1. **Create a Condition Split** :

2. **Define ‹&nbsp;New Contacts&nbsp;›** :

3. **Define ‹&nbsp;Existing Contacts&nbsp;›** :

4. **Implement ‹&nbsp;If/Else&nbsp;› Logic** :

This way, the system can differentiate between new contacts and those already engaging with your content. Let me know if this works for you, or if you’d like more help, I can walk you through it step-by-step!
