New sending domains and IPs have no established reputation with mailbox providers, so sudden high-volume sends are indistinguishable from spammer activity, triggering deferrals, spam folder placement, or outright blocks that can take weeks to recover from.
Use the email-warmup skill to create a 28-day gradual sending volume schedule for your new marketing domain, starting with 50 emails on day 1 and ramping up to full volume by day 29, while prioritizing sends to your most recently engaged contacts.
High-intent search queries and answers about installing and using this skill.
New sending domains and IPs lack established reputation, causing mailbox providers to treat sudden high-volume sends as spam. Gradual volume ramping builds sender trust by slowly increasing daily email throughput to avoid triggering spam filters and reputation damage.
Warm up a dedicated IP by implementing a gradual volume ramp schedule, starting with a low daily volume like 50 emails and increasing throughput over a 28-day period. Enforcing a 2x daily volume increase cap prevents deferrals, blocks, and spam folder placement during IP warmup.
Yes, warming up email domains is required after switching providers, migrating to dedicated IPs, or resuming sends after 30+ days of inactivity. Gradual volume ramps rebuild sender reputation with mailbox providers to prevent spam filter triggers and deliverability damage.
Yes, the email warmup process includes provider-specific guidance for Amazon SES, SendGrid, Postmark, and Resend, providing tailored instructions to leverage each platform's native warmup automation features for marketing bulk, cold outreach, and transactional email streams.
Prevent AI agent email reputation damage by applying specialized guardrails including infrastructure-level rate limits, per-recipient cooldowns, and negative signal monitoring. These safeguards stop accidental volume spikes from agent bugs or loops from triggering spam filters.
The best way to prioritize recipients during email warmup is engagement-based targeting. Send first to your most recently engaged contacts and monitor bounce and complaint rates closely to maintain deliverability and avoid spam folder placement.
