Instantly changed our outbound strategy fundamentally. Unlimited email accounts means we can rotate properly for deliverability. Our agency runs campaigns for 30 clients from one Instantly account. The AI writing for personalized intros is good and the master inbox makes reply management actually manageable at scale.
The email warm-up infrastructure alone is worth the subscription price. Our domain reputation improved dramatically within 3 weeks. Combined with the lead finder database and AI sequence writing, we reduced our tech stack from four tools to one. Exceptional value for outbound-focused sales teams.
Solid platform for cold email at scale. The unlimited accounts feature is the headline differentiator and it works as advertised. Setup takes some technical knowledge around DNS and domain configuration. Once configured correctly, deliverability performance is very strong compared to alternatives we have tested.
