Playbook: move a list to a new ESP without nuking deliverability

Playbook: move a list to a new ESP without nuking deliverability

A cold import to a fresh IP gets you spam-foldered. Sequence it:
— Export with engagement data; import only opens in last 90 days first
— Warm the new sending domain: 500/day, double every 3 days, watch bounce rate
— Re-authenticate SPF, DKIM, DMARC on the new platform before the first send
— Send the dormant segment last, after reputation is established

MailerLite
👍 free to 1k subs, clean automations, $20/mo at 2.5k
👎 strict approval team, can pause your account on import spikes

ConvertKit (Kit)
👍 creator-friendly tagging, good deliverability, visual sequences
👎 $29/mo floor, no native A/B on automations

Verdict: MailerLite if cost rules, Kit if you sell products to a segmented list.

Best for: bloggers leaving Mailchimp's pricing.
