Instantly has more features — lead database, CRM, AI copy, mobile app. But its infrastructure is consumer Gmail with AI warmup that can get your tenant banned. ColdSend uses Azure Communication Services' managed IP pool with auto-swap protection. No per-mailbox fees. No AI warmup risk.
Instantly is the broader platform. It has 450M+ B2B leads, pipeline CRM, AI agents, and mobile apps. For beginners or agencies wanting everything in one place, it makes sense. ColdSend is the deeper infrastructure play. We use Azure Communication Services' managed IP pool where Microsoft handles IP reputation and auto-swaps blacklisted IPs. No AI warmup. No consumer Gmail. No per-mailbox fees. Choose Instantly if you want the most features and do not mind managing consumer Gmail infrastructure. Choose ColdSend if you have been burned by deliverability and want Microsoft to manage your IP layer.
Instantly's base price is just the platform. Every mailbox, lead credit, and advanced feature costs extra. Here is what it actually costs to send.
Instantly's AI warmup simulates fake engagement to trick Gmail into trusting consumer IPs faster. The problem: Google detects this. When caught, your entire Workspace tenant gets flagged, your domains burn, and your campaigns die. This is not theoretical — there are documented cases of Instantly warmup getting tenants banned. ColdSend uses Azure Communication Services' enterprise IP pool. Microsoft manages these IPs and auto-swaps any that get blacklisted. No AI fakery. No tenant bans.
Instantly's Growth plan is $47/mo. But that does not include mailboxes ($4-9/mo each via partners), lead credits, verification, or advanced features. At 50 mailboxes, you are paying $200-450/mo extra — 10x the base plan. ColdSend Growth is $79/mo and includes 400 Azure inboxes. Agency is $199/mo with 800 inboxes. No per-mailbox fees. No credit systems. Flat rate.
With Instantly, you are responsible for monitoring Gmail account health, replacing banned accounts, and managing warmup settings. With ColdSend, you are on Azure's managed IP pool. Microsoft has teams monitoring IP reputation 24/7. If an IP gets flagged, it is swapped before you even notice. You focus on campaigns and copy. Microsoft handles the infrastructure.
Create your account and pick a plan. Growth ($79), Scale ($129), or Agency ($199) — all include Azure ACS inbox creation with pre-warmed IPs.
