WarmupInbox is an email warmup and deliverability tool that builds sender reputation to keep cold email out of spam. A practical starting path:
1. Define the job
One sentence: what does success look like in 30 days?
2. Start small
Free tier or trial first; upgrade at a real limit.
3. Core workflow first
Run one workflow end-to-end, then expand.
4. Measure at two weeks
Off-track? Revisit the alternatives.
