ESP Migration and Integration Services Mailkar Studio Offers
We manage your end-to-end migration and integration, built around your new platform's data model, authentication rules, and deployment workflow.
Subscriber and List Transfer
We migrate your subscribers, lists, and segments into your new ESP and map every field, tag, and custom property, along with your suppression lists and opt-in status, so your data lands with zero loss and stays compliant.
Automation Migration
We rebuild your automated flows and triggers, welcome series, cart recovery, and nurture, on the new platform and test each one end to end, so your customer journeys keep firing exactly as before.
Campaign Data Migration
We carry your historical campaign metrics and engagement history across, so you keep the reporting and audience signals that guide your strategy and protect your email sender reputation.
Landing Pages and Forms
We migrate your landing pages and lead-capture forms, then validate every field and submission, so your lead-generation flows stay live without a gap.
Common ESP Migration Problems We Solve
Most migration failures come from the same few mistakes. Here is what Mailkar Studio prevents after ESP migration your campaign performs from day one.
Broken Automations and Lost Revenue
Flows can stop working silently during the ESP migration and cause lost sales. We rebuild and QA every automation post-migration so customer journeys continue without interruption after migration.
Lost Data and Engagement History
Engagement history and suppression lists are vital for sender reputation. We migrate all consent data, suppression lists, and engagement history intact to protect inbox placement.
Authentication Misconfiguration
Incorrect SPF, DKIM, or DMARC can trigger spam filters or block emails. We verify and fix all authentication to ensure emails reach the inbox instead of spam.
Downtime During the Move
Switching all at once can create delivery gaps. We keep the old ESP active until the new platform is fully validated to prevent downtime and maintain consistent sending.

What Is ESP Migration?
ESP migration is moving your email program, subscribers, templates, automations, and sending setup, from one email service provider to another while protecting deliverability and sender reputation, including rebuilding SPF, DKIM, and DMARC and warming the new setup.
Will Migrating Affect My Email Deliverability?
It can if it is rushed, because a new platform starts with no reputation. We use a staged migration with gradual IP warmup, validate inbox placement at each step, and keep your old ESP available until the move is complete.
How Long Does an ESP Migration Take?
Most migrations take two to six weeks, depending on data volume, the number of automations, and how gradually the new IPs need to warm up. You get a clear timeline in your migration plan before we begin.
Can You Migrate My Automations and Templates?
Yes. We rebuild your templates and recreate your automations to match or improve your current logic, then reconnect your CRM, e-commerce, and analytics tools.
Which Email Platforms Do You Migrate Between?
We work across 50+ email service providers, including Klaviyo, Salesforce, HubSpot, Mailchimp, Zoho, Brevo, SendGrid, ConvertKit, and Marketo, plus niche and custom platforms.
Do You Provide Support After the Migration?
Yes. We monitor reputation and inbox placement after launch and can continue as an ongoing retainer for deliverability, integrations, and optimization, or hand over cleanly with full documentation.
