What is AeroSend?

AeroSend is a managed cold email infrastructure platform engineered to solve persistent deliverability challenges faced by B2B sales teams, lead generation agencies, and outbound-focused founders. Founded by Namit Jindal after a ten-month development cycle addressing systemic deliverability failures in existing providers, AeroSend positions itself as a self-optimizing sending infrastructure that proactively manages IP health, domain reputation, and inbox placement without requiring manual intervention.

Unlike traditional inbox providers that deliver static infrastructure, AeroSend implements dynamic IP rotation, automated warmup adjustment, and real-time performance monitoring to maintain high inbox placement rates across Gmail and Outlook. The platform uses dedicated servers with aged IPs—mature sending infrastructure that carries established reputation from deployment—eliminating the cold-start reputation building period typical of new IP provisioning.

AeroSend serves clients ranging from individual cold emailers to enterprise lead generation agencies, with reported success placing campaigns into inboxes at Pepsi, Shopify, Rolex, Meta, and Amazon. The company achieved 90% client retention by focusing on measurable deliverability outcomes rather than feature volume, delivering average reply rate increases of 1.2x-1.5x after customer migration from previous providers.

Core Services

Domain Procurement & Setup

AeroSend supports both platform-provided domains and BYOD (bring your own domain) configurations. Technical setup—SPF, DKIM, and DMARC authentication—is completed automatically during provisioning, ensuring domains pass modern email authentication requirements from first send. DNS configuration is handled server-side, eliminating manual record editing and reducing setup friction for non-technical operators.

Mailbox Provisioning & Management

Each domain includes 3 inboxes by default, with unlimited domain scaling available based on sending volume requirements. Domains are provisioned on dedicated servers with aged IPs, providing immediate sender reputation advantages over new IP infrastructure. The platform’s one-click inbox creation accelerates fleet expansion as campaigns scale, reducing provisioning time from days to minutes.

Deliverability Operations

AeroSend includes free inbox warmup via premium third-party tools (Warmupinbox.com), gradually building sending volume and engagement patterns to establish domain trust with ISPs. The platform implements dynamic warmup volume adjustment—if a domain’s performance declines, warmup settings automatically recalibrate to accelerate reputation recovery. Burner accounts run continuously in the background to absorb negative signals and protect core sending domains from reputation damage.

Proactive IP rotation monitors sending performance at the IP level. When the system detects degradation, it rotates the affected domain to a fresh IP before deliverability impact becomes material. This prevents cascading reputation failures that typically require weeks to resolve manually.

Bounce rate analysis watches for domain-rejected bounce spikes—a leading indicator of blocklist additions or authentication failures. When abnormal patterns are detected, the platform alerts operators and adjusts sending velocity to prevent long-term reputation damage.

Monitoring & Compliance

AeroSend conducts weekly inbox placement tests on all active domains, sending test emails to major ISPs (Gmail, Outlook, Yahoo) and measuring inbox vs. spam folder placement. If any domain begins landing in spam, operators receive immediate alerts with recommended remediation actions. The domain performance comparison dashboard benchmarks all domains side-by-side, surfacing underperformers and enabling targeted intervention before campaign-wide impact occurs.

All domains ship with SPF, DKIM, and DMARC configured to comply with modern authentication standards (including Gmail and Yahoo’s 2024 sender requirements). The platform does not explicitly advertise GDPR or CAN-SPAM compliance tooling, though proper authentication is foundational to meeting these requirements.

Integration Ecosystem

AeroSend integrates natively with popular cold email sequencers including Smartlead, Instantly, and most IMAP/SMTP-compatible platforms. Once inboxes are provisioned and warmed, operators connect them to their sequencer of choice and deploy campaigns immediately. No proprietary sending interface is required—AeroSend functions as infrastructure-as-a-service rather than an all-in-one campaign tool.

Pricing & Engagement Models

AeroSend does not publish public pricing, requiring prospective customers to schedule a consultation for custom quotes. The pricing model is based on domain and inbox count, with each domain including 3 inboxes. Organizations can scale domain count to match sending volume requirements (e.g., 60-75 emails/day per domain recommended for optimal deliverability).

No free trial is available due to the high infrastructure provisioning costs associated with aged IP servers and dedicated infrastructure. The company positions this as necessary to maintain quality and prevent abuse, though it creates a barrier for operators seeking proof-of-concept testing before commitment.

Enterprise engagement is available for agencies and high-volume senders requiring white-label infrastructure, custom SLAs, or dedicated account management. Pricing for these arrangements is negotiated based on scale and service requirements.

The absence of transparent pricing may deter self-service buyers and smaller teams operating on fixed budgets. Organizations should request detailed cost breakdowns—including per-domain pricing, setup fees, and warmup tool costs (if unbundled in future)—during sales conversations to ensure alignment with budget constraints.

Best Fit For

AeroSend is optimized for:

  • B2B lead generation agencies managing cold email infrastructure for multiple clients who prioritize deliverability over feature breadth
  • Outbound sales teams sending 60-75 emails/day per domain (multi-domain fleets) requiring automated reputation management
  • Founders and operators migrating from underperforming providers experiencing spam folder placement or low reply rates
  • High-volume senders targeting Gmail and Outlook recipients where inbox placement directly impacts pipeline velocity
  • Teams lacking technical deliverability expertise who need self-optimizing infrastructure rather than manual monitoring tools

AeroSend is less suitable for:

  • Budget-conscious startups requiring transparent pricing or free trials before commitment
  • Organizations preferring self-service onboarding without sales consultation
  • Senders requiring flexible inbox-to-domain ratios (platform defaults to 3 inboxes per domain)
  • Teams seeking all-in-one campaign management tools (AeroSend is infrastructure-only)
  • Operators requiring extensive third-party validation and review volume before vendor selection

Onboarding & Operations

Timeline: Onboarding duration is not publicly specified but is described as rapid due to automated technical setup. DNS configuration, inbox provisioning, and warmup tooling activation are handled server-side, reducing time-to-first-send compared to manual configuration workflows.

Warmup Period: Inboxes undergo automated warmup via premium tools included at no additional cost. Duration is not explicitly stated but follows industry-standard 2-4 week ramp schedules. Dynamic warmup adjustment extends or compresses this timeline based on real-time domain performance.

Integrations: Once inboxes complete warmup, operators connect them to Smartlead, Instantly, or any IMAP/SMTP-compatible sequencer. AeroSend provides IMAP credentials and SMTP settings for universal compatibility.

Ongoing Collaboration: The platform operates as a managed infrastructure service—technical optimizations (IP rotation, warmup adjustment, bounce monitoring) run automatically without operator intervention. Weekly inbox placement reports provide transparency into deliverability health, but day-to-day management is hands-off. Operators focus on campaign strategy, list quality, and messaging while AeroSend handles infrastructure reliability.

Support Model: The company emphasizes founder-led service (Namit Jindal has personally assisted 50+ B2B companies) and consultative partnerships rather than self-service support portals. This approach suits operators seeking strategic deliverability guidance but may not scale for agencies managing hundreds of client domains independently.

Evaluating AeroSend? Request a detailed pricing proposal including per-domain costs, setup fees, and any volume-based discounts for multi-domain fleets. Ask for case studies or references from similar organizations in your vertical, and clarify SLA commitments around inbox placement rates and IP rotation response times. If you’re migrating from a provider experiencing deliverability degradation, AeroSend’s self-optimizing infrastructure and aged IP inventory may justify the premium over static alternatives.
