When to Choose Each Tool
You need accurate engagement data — not inflated numbers. Agencies that manage campaigns for clients need real open rates they can stand behind. Bot-filtered data via Postmark webhooks is the differentiator here.
You prioritize creative personalization — dynamic images and video — over data accuracy. High-touch outbound with a consultative sales motion (product demos, fractional AE outreach) is where Lemlist's assets shine.
