Instantly

How we use it

We use Instantly for managed cold email campaigns on behalf of clients doing outbound prospecting. It handles sending across multiple inboxes with automatic warmup to protect deliverability, A/B testing for subject lines and message variants, and a built-in lead database for sourcing prospect lists. The deliverability infrastructure is the main reason we chose it over alternatives.
