It prepares your accounts by gradually increasing sending volume and simulating real email activity with opens and replies.<\/p>\n<div class=\"notification-block learn\">\n<div class=\"notification-block__icon\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/snov.io\/knowledgebase\/wp-content\/themes\/knowledgebase-n\/assets\/img\/fluent_chat-warning-16-regular.svg\" alt=\"learn\" width=\"32\" height=\"32\" \/><\/div>\n<div class=\"notification-block__text\">Warm-up is especially important if you're creating a new setup or testing new ICP segments. After the initial period, keep warm-up active at all times to maintain deliverability.<\/div>\n<\/div>\n<p data-start=\"656\" data-end=\"771\">We recommend warming up any existing accounts or done-for-you mailboxes before starting outreach. Run accounts through the initial warm-up period and do not send outreach during this time to get the full effect:<\/p>\n<ul>\n<li data-section-id=\"gnp5yw\" data-start=\"921\" data-end=\"970\"><strong data-start=\"923\" data-end=\"935\">4 weeks:<\/strong> for new domains and new accounts<\/li>\n<li data-section-id=\"jreh9n\" data-start=\"971\" data-end=\"1044\"><strong data-start=\"973\" data-end=\"985\">2 weeks:<\/strong> for existing accounts or accounts inactive for some time<\/li>\n<\/ul>\n<p data-start=\"1439\" data-end=\"1497\">If you need to start sooner, add accounts to campaigns gradually:<\/p>\n<ul data-start=\"1498\" data-end=\"1561\">\n<li data-section-id=\"e78kcf\" data-start=\"1498\" data-end=\"1534\">add a few mailboxes after 1 week of warm-up<\/li>\n<li data-section-id=\"1peyo79\" data-start=\"1535\" data-end=\"1561\">add more after 2 weeks warm-up<\/li>\n<\/ul>\n<p data-start=\"899\" data-end=\"1032\"><span style=\"font-weight: 400;\">Warm up more mailboxes to always have additional senders in your back-up. When you need to reach more prospects, add warmed-up senders from your back-up pool, not completely new accounts.<\/span><\/p>\n<p data-start=\"899\" data-end=\"1032\">To scale easier later, get additional done-for-you accounts and put them on warm-up.
