Switch from MailerLite to AlpacaRelay

MailerLite exports your contacts as CSV through Audience > All subscribers > Export audience. The file includes email, name, custom fields, and subscription status. AlpacaRelay accepts CSV imports directly—upload the file, map your fields, and AlpacaRelay handles the rest. This moves step 2 (data structuring) from your hands to AI, which auto-detects field types and flags missing compliance markers. Note: MailerLite's custom fields map to AlpacaRelay's segments, but any automation logic tied to those fields must be rebuilt—automations do not export as code. Plan 2-3 hours for this rebuild if you have complex workflows.

When you import from MailerLite, AlpacaRelay respects the subscription status already in your CSV—confirmed subscribers remain confirmed, unconfirmed contacts stay unconfirmed. You do not re-trigger double opt-in emails on import. However, if your MailerLite export marks all contacts as confirmed but you want to verify them in AlpacaRelay, you can trigger a re-confirmation workflow after import. This is optional and depends on your compliance posture. AlpacaRelay's Structural Compliance dimension (part of the 8-Dimension Email Quality Framework) scores your import for consent signals—templates imported from MailerLite that lack clear consent language will score lower on this dimension and flag for review before send.

Expect 1-2 weeks total. Week 1: export MailerLite CSV (30 min), audit and upload to AlpacaRelay (1-2 hours), rebuild automations in AlpacaRelay (3-5 hours depending on complexity), and audit templates. Week 2: run both platforms in parallel (see next FAQ for cost implications) and warm up AlpacaRelay's sending IP to avoid deliverability dip. Do not cut off MailerLite until week 3, after AlpacaRelay has sent at least 5,000 emails and ISPs have recognized your new IP as legitimate. Industry benchmarks show 2-4 week warm-up periods are standard during sender infrastructure migration. Rushing this increases bounce rates and unsubscribe rates by 15-25%.

Yes, you will pay both platforms during the overlap—this is a real cost, and we are being honest about it. Run both for 2-4 weeks minimum. Send your most engaged segment (top 20% by open rate) through AlpacaRelay first to build IP reputation fast. Monitor deliverability metrics: once AlpacaRelay achieves 85%+ inbox placement (vs MailerLite's typical 83.5% industry baseline per Validity, 2025), migrate the remaining subscribers. The parallel cost is typically $50-200/month depending on list size, but the payoff is avoiding a 10-30% temporary dip in opens and clicks. After week 4, cut off MailerLite entirely. This migration step—deciding which segment to move first and monitoring IP warmup—is traditionally manual labor that AlpacaRelay's AI now handles with predictive warmup scoring.

Every template you import is instantly scored across the 8-Dimension Email Quality Framework—Structural Compliance, CTA Clarity, Visual Hierarchy, Mobile Responsiveness, Personalization Depth, Subject Line Effectiveness, Sender Credibility, and Engagement Potential. A fashion brand template scoring EQS 80+ typically generates $800-2,000/month more revenue than baseline templates due to higher click-through rates (Personalized CTAs convert 202% better than generic versions per HubSpot, 2025). When you import from MailerLite, templates scoring below 75 are flagged with specific improvement suggestions—the AI then rewrites underperforming sections and re-scores in real time. This moves step 5 (template optimization) from manual testing to automated scoring. A template scoring 65 on import might reach 82-85 after AI-guided rewrites, which translates to measurable CTR uplift within 2-3 sends. Subject lines benefit most: AI-generated alternatives increase opens by 5-10% on average (Knak, 2026), and AlpacaRelay tests variations automatically on your next send.
