Need help If a company has 2–3 contacts, how can I ensure that only one specific mailbox in Instantly is used to email all contacts from that same company

Hi all, need help If a company has 2–3 contacts, how can I ensure that only one specific mailbox in Instantly is used to email all contacts from that same company? Basically, I want to avoid multiple mailboxes reaching out to different contacts within the same company. Is there a way to set this up on the Clay side? Because I confirmed on instantly side it's not possible. We can only limit how many emails are sent to a company per day.

Ya I understand there isn't a built in feature

I am trying to understand if there is a workaround with custom logic that can be done on clay side to ensure this

Yes I understand and I agree but this will probably limit our outreach

For eg we want to reach out to decision makers right

So both CEO and Head of Marketing are relevant

We don't want to chose only one

For this use case How should I structure by campaigns on instantly

The initial structure was by Region (APAC, LATAM, EMEA)

Should I create campaigns based on Region+ BDR?

Eg: APAC - BDR 1 APAC - BDR 2

EMEA - BDR 1

Will this work?

Hello, on clay’s side there isn’t a built in feature to assign a specific mailbox per company. the usual approach is to manage this in your workflow either by tagging contacts per company and filtering them before sending or by using a custom script to ensure all contacts from the same company go through the same mailbox since Instantly can’t handle it either a workflow level solution is the best workaround.

Hey Noor, I have an idea on it but it depends a bit on how you use instantly. If you have 1 campaign that you run everyone through you could duplicate that campaign and assign each domain its own campaign, then as part of your clay set up, you have a "lookup" table which just sorts which domain goes to which campaign, (if it doesn't find it in that table it would pick one at random and if it does find it in that table it uses that campaign) lots of set-up but doable
