Integrate Brevo into OpenAI Ads custom audiences
Brevo already holds your contacts, your lists, the attributes you set, and a read on who still engages. Connect it to Bluegrass and those contacts become OpenAI Ads audiences you can target or hold out. Each one gets its own bid.
Your data is only used to build your audiences · never sold
What you can do with Brevo on OpenAI Ads
Brevo, the platform many businesses knew as Sendinblue, is where they keep contacts, lists, and the custom attributes that drive their email and automations. That structure already encodes who is engaged, who is new, and who has gone inactive. Bluegrass reads your contacts, lists, attributes, and segments (not your message content) and uses them only to build and sync custom audiences on OpenAI Ads.
Once Brevo is connected you can split contacts by how they relate to your list. Engaged subscribers, members of a specific list, brand-new contacts, and people who have stopped opening each become a separate audience, and you decide whether any one of them gets a higher bid or sits out of prospecting.
Custom audiences you can build from Brevo
Each one can be a target audience with its own bid, or a suppression list you hold out from prospecting.
Target the right people, exclude the rest
Re-engage and bid more
Put more budget behind inactive contacts and the lists you care about most. These people already opted into your email, so a measured bid increase usually pays back faster than reaching strangers cold.
Stop paying for people you already reach
Hold new contacts and your most active subscribers out of acquisition. You can already email them, so that ad budget moves to people who do not know you yet.
Common ways advertisers use Brevo
Reactivate inactive contacts
Build an audience of contacts who have not opened in six months and raise your bid to reach them on OpenAI Ads while a re-engagement campaign runs in Brevo.
Bid by list or attribute
Pick a list or a custom attribute that signals intent, like a recent download or a chosen plan interest, and set a higher bid for those contacts than for your general list.
Suppress new contacts
Mark contacts added in the last two weeks as a suppression audience so prospecting ads stop spending on people already in your welcome flow.
Connect Brevo in three steps
Connect Brevo
Authorize Bluegrass with read-only access to your contacts, lists, attributes, and segments. Bluegrass never reads your message content or campaign reports.
Pick the segment
Choose a list or saved segment, like engaged in the last 30 days or contacts matching an attribute. Bluegrass takes the matching contacts and uses them only to build that audience and match it to OpenAI Ads.
Set a bid and launch
Mark the audience as a target or a suppression, give it a bid adjustment, and layer day parting on top before it goes live.
Your data stays yours
Bluegrass only uses your customer data to build and update your audiences on OpenAI Ads. We never sell it or use it for anything else, and you can disconnect any time.
- Bluegrass reads contacts, lists, attributes, and segments, not your message content or campaign reporting beyond engagement state
- Bluegrass uses your contacts only to build and update your audiences on OpenAI Ads. It is never sold or used for anything else, and you can disconnect or remove it any time
- Audiences refresh as your lists and attributes change, so a contact who goes inactive moves into your re-engagement audience automatically
Pair it with a goal and a schedule
Nurture and convert leads
Your CRM already knows which leads are warm and which are not. Push those segments into OpenAI Ads so the right message reaches each nurture stage, and hold your closed-won accounts out so you stop paying to sell to people who already signed.

Audiences decide who you bid on. Day parting decides when, so budget lands in the hours that convert.

Brevo and OpenAI Ads, answered
What Brevo data does Bluegrass use?
Your contacts plus the lists, attributes, and segments you have built: who is on which list, what their attributes say, who is engaged, and who has gone inactive. Bluegrass never reads your message content.
Can I suppress my current contacts from ads?
Yes. Mark a list, a segment, or your most active subscribers as a suppression audience and they are held out of prospecting, so you stop paying to reach people you can already email.
Does the audience stay fresh as my contacts change?
Yes. Audiences refresh as Brevo changes. A contact who stops opening drops out of your engaged list and moves into your re-engagement audience on the next sync.
Is my contact data safe?
Yes. Bluegrass uses your contacts only to build and update your audiences for OpenAI Ads. It is never sold, shared, or used for anything else. You stay in control, and you can disconnect Brevo or remove your data any time.
