From Sendinblue to AlpacaRelay

Step-by-Step Migration

1

Export Your Contacts from Sendinblue

Log into your Sendinblue account and navigate to Contacts > All Contacts. Click the checkbox to select all contacts, then choose Export > Export as CSV. Download the file with all contact fields intact (email, first name, tags, custom attributes). This step transfers data ownership from manual spreadsheet management to AI-driven audience intelligence. Sendinblue exports take 2-5 minutes depending on list size; you've just eliminated the first manual handoff in your workflow.

2

Create Your AlpacaRelay Account and API Setup

Sign up at alpacarelay.com and complete onboarding. Navigate to Account Settings > API Keys and generate your primary API key — you'll need this for contact imports and template scoring. Store this key securely; it's the single authentication point for all AI automation flows moving forward. This step activates the 7-Step Expertise Chain: from here, AI begins taking on responsibility for data validation, template scoring, and deliverability monitoring.

3

Import Contacts and Enable AI Data Mapping

In AlpacaRelay, go to Audience > Import Contacts > CSV Upload. Select your Sendinblue export file and map columns: email → Email, First Name → First Name, Tags → Tags, and any custom fields to their AlpacaRelay equivalents. AlpacaRelay's AI automatically detects and corrects common formatting errors (extra spaces, invalid emails, duplicate entries). Hit Import and the system deduplicates, validates, and enriches your contact records in real time — what took you 30-45 minutes of manual cleanup in Sendinblue now happens in the background.

4

Transfer and Upgrade Your Email Templates

Log back into Sendinblue and navigate to Campaigns > Templates > select a template > Design > Export HTML. Save each template as .html. In AlpacaRelay, go to Templates > Import Template and upload each HTML file. This is where the 8-Dimension Email Quality Framework kicks in: every imported template is instantly scored across Deliverability, Mobile Render, CTA Clarity, Personalization Depth, Visual Hierarchy, Copy Effectiveness, Brand Consistency, and Structural Compliance. You'll see an Email Quality Score (EQS) for each template (typically 65-78 for Sendinblue imports). AI recommendations appear automatically — you review and apply them in seconds rather than hours of manual A/B testing.

5

Rebuild Key Automations (Welcome, Abandoned Cart, Re-engagement)

Sendinblue automations cannot be exported — you must rebuild them in AlpacaRelay, but the payoff is substantial. In Sendinblue, open Automation > select each workflow and screenshot the triggers and email sequence. In AlpacaRelay, go to Automations > Create New Workflow > select trigger (e.g., new subscriber, cart abandonment). AlpacaRelay's AI does two things your manual rebuild cannot: it auto-sequences your emails (e.g., converts a 1-email welcome into a 3-email sequence) and scores every email in the flow individually. Your welcome sequence, for example, gets upgraded from a static template to a personalized, multi-touch sequence with EQS improvements at each step. What took 3-4 hours of manual workflow design in Sendinblue now takes 45-60 minutes because AI handles the sequencing logic.

6

Update DNS/DKIM/SPF and Begin Parallel Send Testing

In AlpacaRelay, go to Account Settings > Sender Authentication > DNS Records. Copy the DKIM and SPF records provided. Log into your domain registrar (GoDaddy, Cloudflare, etc.) and add these records to your DNS. This process typically takes 24-48 hours to propagate. Important: do not immediately switch all sends to AlpacaRelay. Run both platforms in parallel for 2-4 weeks. Send your first 10% of campaigns from AlpacaRelay to your most engaged subscribers, monitor deliverability (AlpacaRelay's dashboard shows real-time inbox placement), then gradually increase volume. This warm-up period is non-negotiable — ISPs trust Sendinblue's IP reputation, and moving to a new IP requires a 2-4 week rebuild window.

What You Gain by Switching

Sendinblue users face a fundamental expertise gap that costs them thousands annually in invisible labor. According to Validity's 2025 Email Deliverability Benchmark Report, the average global inbox placement rate sits at just 83.5% — meaning 1 in 6 marketing emails never reaches the inbox. Yet Sendinblue provides no pre-send quality scoring to help you optimize before hitting send. You're flying blind on deliverability, spending 8-12 hours monthly managing campaigns, tweaking subject lines, and troubleshooting delivery issues. At $62/hour for marketing expertise, that's $7,440 annually in hidden labor costs just to maintain basic email performance.

AlpacaRelay's 8-Dimension Email Quality Framework eliminates this guesswork by moving expertise from your plate to AI. Where Sendinblue requires you to manually optimize subject lines (step 2 of our 7-Step Expertise Chain), AlpacaRelay's AI generates and scores alternatives automatically. Personalized emails achieve 29% higher open rates and 41% higher click-through rates compared to non-personalized versions (Litmus/Instapage, 2025), yet Sendinblue's personalization requires manual token insertion. Our AI handles dynamic personalization depth scoring, reducing your monthly campaign management from 10+ hours to under 30 minutes. This shift from manual optimization to automated expertise represents $7,200+ in annual labor savings.

Pricing transparency becomes critical as your list grows beyond Sendinblue's deceptive starter tiers. While exploring Sendinblue alternatives, many users discover hidden costs in advanced automation features and email volume overages. Our pricing structure eliminates surprise billing jumps — you see exactly what you'll pay as you scale. Combined with industry-calibrated email templates that score 85+ on our Email Quality Score out of 100, you're getting enterprise-grade infrastructure without enterprise complexity. According to Knak's 2026 Email Creation & AI Statistics, AI-generated subject lines increase open rates by up to 22%, with typical improvements of 5-10% — capability that Sendinblue's manual approach simply cannot match.

The analytics upgrade alone justifies migration costs within 90 days. Sendinblue's open rate inflation from Apple Mail Privacy Protection creates false performance signals, leading to poor optimization decisions. AlpacaRelay's honest analytics separate real engagement from privacy-protected opens, giving you accurate campaign intelligence. When comparing all available email marketing tools, this analytical honesty becomes a competitive advantage. You'll lose Sendinblue's SMS integration and some advanced landing page features during migration — we're transparent about these trade-offs in our detailed Sendinblue vs AlpacaRelay comparison. However, the expertise replacement model means your email marketing runs itself, freeing up 120+ hours annually for revenue-generating activities instead of campaign maintenance.

The compound effect of automated expertise creates exponential returns. While Sendinblue users manually A/B test subject lines (39% of companies test subject lines first, according to LLCBuddy's 2026 A/B Testing Statistics), AlpacaRelay's AI runs continuous optimization across all 8 quality dimensions simultaneously. Your imported templates immediately receive EQS scoring, identifying improvement opportunities that would take weeks to discover manually. This systematic approach to email quality, combined with our comprehensive migration guides, ensures you're not just switching platforms — you're upgrading from manual email management to AI-driven marketing automation that scales with your business growth.

Common Migration Concerns (Addressed)

Will I lose subscribers during the migration? This is the most frequent worry we hear from Sendinblue users, and the answer is definitively no. Sendinblue's CSV export preserves every data field — contact information, subscription status, tags, custom fields, and engagement history. Our AI migration assistant automatically maps these fields to AlpacaRelay's structure, ensuring nothing gets lost in translation. You'll have the same subscriber count on day one, with all segmentation intact. The 8-Dimension Email Quality Framework immediately begins analyzing your imported contact data to identify your most engaged segments, actually giving you better visibility into subscriber quality than before.

Will my deliverability drop after switching? Here's where we practice radical honesty: yes, temporarily. A 2-4 week warm-up dip is normal and unavoidable with ANY migration between email service providers. ISPs like Gmail and Outlook need to build trust with AlpacaRelay's sending infrastructure, regardless of how pristine your reputation was with Sendinblue. We do not pretend otherwise or promise 'seamless deliverability transfer' like some competitors. However, our Email Quality Score (EQS) system accelerates recovery by ensuring every email meets the highest deliverability standards. According to Validity's 2025 Email Deliverability Benchmark Report, the average global inbox placement rate is 83.5%, meaning 1 in 6 marketing emails never reaches the inbox. Our quality-first approach consistently achieves 94%+ placement rates once the warm-up period concludes.

What happens to my existing automations? Another area where honesty matters: they need rebuilding. Sendinblue's automation logic cannot be directly imported to any platform — the workflow structures are proprietary. But here's what changes the equation: our AI doesn't just recreate your automations, it upgrades them. Your welcome email becomes a scored 3-email sequence. Your basic newsletter becomes AI-optimized with personalized subject lines that achieve 5-10% higher open rates (Knak Email Creation & AI Statistics, 2026). That manual cart abandonment reminder you never built? It becomes a one-click Tier 1 automation. Each rebuilt sequence gets individual EQS scores on every email, typically outperforming the originals by 15-25% within the first month.

How long will the migration actually take, and what's the real cost? For basic contact imports and simple automations, plan 30 minutes. For complex multi-step sequences with conditional logic, allow 2-3 hours spread across a week. Here's our recommendation that saves headaches: run both platforms in parallel for 2-4 weeks. Yes, that means paying for both temporarily — approximately $50-200 in overlap costs depending on your Sendinblue plan. But consider the math: AlpacaRelay's automation depth saves 15-25 hours monthly in manual email management. At $50-75/hour for marketing labor, that's $750-1,875 in monthly savings. The parallel run also eliminates deliverability anxiety — you can gradually shift traffic to AlpacaRelay starting with your most engaged segments, then migrate the full list once performance stabilizes.

Migration FAQ
What format does Sendinblue export contacts in, and will double opt-in transfers?
Sendinblue exports your contact list as CSV from Contacts > All Contacts > Export. The export includes email, first/last name, and custom attributes. Double opt-in status does NOT transfer automatically—you'll need to map the opt-in field manually during import, or re-verify contacts to comply with GDPR and CAN-SPAM. AlpacaRelay honors your existing list's consent state, but verification is your responsibility. This is Step 1 of the 7-Step Expertise Chain: data preparation. After import, the AI handles Steps 2-7 (segmentation, scoring, send optimization).
Where do I find my Sendinblue API key, and do I need it for migration?
Your Sendinblue API key is in Account Settings > API > Create API Key. You do NOT need an API key for a standard CSV export migration—you can download contacts manually via the UI. However, if you're migrating automations or tracking historical data, an API key enables a programmatic pull. Most migrations use the manual CSV route (30 minutes) rather than API integration (1-2 hours setup). AlpacaRelay's AI then rebuilds your automations from scratch, improving them with EQS scoring on each step (that's Step 3 of the expertise chain: automation design).
How long does the full migration take, and what's the real cost of running both platforms in parallel?
Contact migration takes 30 minutes to 2 hours depending on list size and attribute mapping. Template migration adds 1-3 hours (export templates as HTML from Campaigns > select each > Export Template). Automation rebuild is 2-4 hours for complex workflows. The parallel run costs overlap: you'll pay both Sendinblue and AlpacaRelay fees for 2-4 weeks (the typical deliverability warm-up window). Expect your monthly bill to increase by 30-50% during transition, then drop by 20-30% once you sunset Sendinblue—because AlpacaRelay's AI handles template optimization, A/B testing, and send timing automatically (Steps 4-7 of the expertise chain). Plan for this cost trade-off upfront.
What happens to my deliverability when I switch sending infrastructure?
When you move from Sendinblue's IPs to AlpacaRelay's sending infrastructure, ISPs reset their trust model. Expect a 10-20% temporary deliverability dip for 2-4 weeks while new IPs build reputation. This is normal and recoverable—not a platform failure. During parallel run, send your most engaged segment (top 20% by open rate) through AlpacaRelay first. Once deliverability stabilizes (typically week 3), migrate the remaining list. Industry data shows average global inbox placement is 83.5%, with 1 in 6 marketing emails never reaching the inbox (Validity Email Deliverability Benchmark Report, 2025). AlpacaRelay's EQS scoring helps you rebuild above that baseline by identifying delivery-risk factors before send.
How does EQS scoring improve my imported templates, and what revenue impact should I expect?
When you import templates, AlpacaRelay instantly scores each against the 8-Dimension Email Quality Framework: Subject Line Impact, CTA Clarity, Visual Hierarchy, Structural Compliance, Mobile Responsiveness, Personalization Depth, List Segmentation Alignment, and Send Timing Optimization. Templates scoring 80+ EQS (on 100-point scale) typically generate 15-25% higher engagement. Based on AlpacaRelay analysis, templates with EQS 80+ generate approximately $800-2,000 additional monthly revenue per 10,000 subscriber segments compared to unscored templates—through higher opens, clicks, and conversions. This is Step 5 of the expertise chain: performance optimization. The AI identifies weak dimensions (e.g., 'CTA Clarity 6.2/10'), suggests rewrites, and re-scores in real-time. You go from managing template quality manually to letting AI handle it.
Can I A/B test during migration, and what's the best strategy for comparing Sendinblue vs. AlpacaRelay performance?
Yes—A/B testing during parallel run is exactly what we recommend. Send the same campaign from both platforms to similar audience segments (split your most engaged 10,000 contacts 50/50). Compare open rate, click-through rate, and unsubscribe rate over 2-4 weeks. AI-generated subject lines increase open rates by 5-10% on average, with improvements up to 22% in high-variation tests (Knak Email Creation & AI Statistics, 2026). AlpacaRelay's AI generates subject lines for every A/B test, so you'll likely see AlpacaRelay outperform within 2 weeks. Track these metrics in both platforms, then migrate remaining contacts to the winner. This hybrid approach (Step 6: performance comparison) removes migration risk and gives you data-driven confidence before full cutover.
