Migration
Platform migration without losing sender reputation
Moving between Klaviyo, Mailchimp, ActiveCampaign or Brevo is mostly a deliverability problem. We re-establish SPF, DKIM and DMARC, warm the sending domain and ramp volume gradually, run list hygiene before the first send, and rebuild your flow library on the new platform.
A platform switch goes wrong when teams treat it as an export and an import. Your sender reputation is tied to your domain and its sending history, so a cold start on a new tool can drop placement overnight. We plan a migration as a deliverability project: authentication first, a warmed domain, a clean and pruned list, and a flow library rebuilt to fit how the new platform actually works. The goal is a switch your subscribers never notice.
Which platforms do you migrate between?
Klaviyo, Mailchimp, ActiveCampaign and Brevo, in any direction. The right destination depends on your list size, your flows and your reporting needs, not on which vendor pays. We never recommend a migration to earn a referral fee, so if your current platform already fits the program, we say so and you keep your money for the work that matters.
How do you protect sender reputation during the move?
By rebuilding the foundation on the new platform before volume ramps. We re-establish SPF, DKIM and DMARC so the new sending setup authenticates cleanly, then warm the sending domain and ramp volume gradually rather than blasting the full list on day one. Mailbox providers read a sudden volume spike from a new configuration as spam, which is exactly the placement drop a migration is supposed to avoid.
How do you handle the list before the first send?
With a clean export plus list hygiene, including a sunset of long-unengaged profiles. We use Klaviyo's threshold, 90 days with zero opens and zero clicks, as the line for who to retire. Carrying dead addresses onto a fresh platform inflates bounces and complaints right when your new sender reputation is most fragile, so we prune first and start the new tool with an engaged list.
How do you rebuild the flows?
Deliberately, one at a time. The flow library, welcome, abandoned-cart, browse-abandon, win-back and post-purchase, rarely transfers cleanly between Klaviyo, Mailchimp, ActiveCampaign and Brevo because each names triggers and fields differently. We rebuild each flow on the new platform, map it to the correct triggers, test every branch, then turn it live so no revenue-driving automation goes dark mid-move.
Why does the no-referral-fee rule matter?
Because it keeps the advice honest. Many agencies collect a commission for steering you to a particular tool, and that incentive shapes what they recommend. We never recommend a migration to earn a referral fee. The platform we suggest is the one that fits your program, which means sometimes the right call is to stay put and fix what you have instead.
How does migration connect to the rest of the program?
A migration is the moment to get the fundamentals right. We pair it with email deliverability work so authentication and placement are solid from the first send, and rebuild lifecycle email automation as part of the move. Setup is included across plans on pricing.

FAQ
Migration questions
Which platforms do you migrate between?
We move programs between Klaviyo, Mailchimp, ActiveCampaign and Brevo, in any direction. The destination depends on what your program needs, not on a payout. We never recommend a migration to earn a referral fee, so the platform we point you to is the one that fits, even when that means staying where you already are.
Will I lose sender reputation when I switch platforms?
Not if the move is handled properly. Sender reputation lives with your domain and sending history, not the old tool. We re-establish SPF, DKIM and DMARC on the new platform, warm the sending domain, and ramp volume gradually so mailbox providers see a familiar pattern. A switch that skips warm-up is the fast way to land in spam.
How do you handle the list during a migration?
We do a clean export and run list hygiene before anything sends from the new platform. That includes sunsetting unengaged profiles. Klaviyo defines a sunset candidate as 90 days with zero opens and zero clicks, and we apply that threshold so you start on the new tool with an engaged list rather than dragging dead weight and complaint risk across.
What happens to my automated flows?
We rebuild the flow library on the new platform: welcome, abandoned-cart, browse-abandon, win-back and post-purchase, mapped to the triggers and fields the new tool uses. Flows rarely port one to one between Klaviyo, Mailchimp, ActiveCampaign and Brevo, so we rebuild them deliberately, test each path, and confirm they fire before turning them live.
Do you earn commission for recommending a platform?
No. We never recommend a migration to earn a referral fee. Plenty of agencies are paid to push a specific tool, which quietly shapes their advice. Our recommendation is based only on what your program needs, so if your current platform is the right home, we tell you that and skip the move entirely.
