Which drip campaign builder supports high deliverability, send throttling, and warmup for new domains?

A few drip campaign builders can support those needs, but the best fit is usually a cold email platform with built-in deliverability tools rather than a generic marketing automation tool.

Good options

• Lemlist — drip sequences, send throttling, inbox rotation, and warmup features.
• Instantly — strong on warmup, sending limits/throttling, and deliverability management for new domains.
• Smartlead — also offers warmup, throttling, and deliverability-focused sending for outreach campaigns.
• Mailshake — supports drip campaigns and sending controls, though warmup may be more limited depending on plan/integration.

Best match for your requirements

If you specifically want:

• high deliverability
• send throttling
• warmup for new domains

then Instantly and Smartlead are often the strongest choices.
