From Manual Work to AI-Powered Expertise

Step-by-Step Migration

1

Export Your Contacts from Sendinblue

Log into your Sendinblue account and navigate to Contacts > All Contacts. Select all contacts (or filter by segment), then click Export > Download as CSV. Save the file with your subscriber data, including email addresses, first names, tags, and custom fields. This export typically takes 2-5 minutes depending on list size. You're moving data ownership from manual spreadsheet management to AI-driven infrastructure—AlpacaRelay takes over list hygiene and validation from here.

2

Create Your AlpacaRelay Account

Visit alpacarelay.com and sign up with your business email. Follow the onboarding wizard to set up your workspace, billing, and initial authentication. Choose your sending domain (e.g., mail.yourcompany.com) and verify ownership. This step typically takes 10–15 minutes. You're activating the AI expertise chain: from Step 2 forward, AlpacaRelay's systems continuously monitor your sending reputation, deliverability metrics, and compliance posture—tasks that previously consumed 3–5 hours per month in manual audits.

3

Import Contacts and Map Tags to AlpacaRelay

In AlpacaRelay, go to Audience > Import Contacts > Upload CSV. Select your Sendinblue export file. AlpacaRelay's AI automatically detects column headers (email, first name, tags) and maps them to the correct fields. Review the preview, confirm the mapping, and click Import. The system deduplicates entries, validates email addresses against compliance rules (critical for the November 2025 Google/Yahoo enforcement), and assigns each contact a deliverability score. This step typically takes 5–10 minutes for upload, plus 2–3 minutes for AI processing. You're outsourcing data quality work: AI handles validation, deduplication, and hygiene scoring that previously required manual review.

4

Export Templates from Sendinblue and Import into AlpacaRelay

In Sendinblue, navigate to Campaigns > Templates > select a template > Edit > Export as HTML. Save each template. Then in AlpacaRelay, go to Templates > Import > Upload HTML. Paste or upload each HTML file. AlpacaRelay's AI instantly scores every template across the 8-Dimension Email Quality Framework (Deliverability, Mobile Render, CTA Clarity, Personalization Depth, Visual Hierarchy, Copy Effectiveness, Brand Consistency, Structural Compliance). Each template receives an Email Quality Score (EQS) on a scale of 0–100. Most Sendinblue templates score 65–78 initially; AlpacaRelay's optimization engine often surfaces quick fixes that push scores to 82–91 within minutes. You're shifting from manual template tweaking to AI-driven quality scoring and upgrading.

5

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

Sendinblue automations cannot be directly exported; you must rebuild them in AlpacaRelay. Start with your Welcome Sequence: In AlpacaRelay, go to Automations > Create New > Welcome Series. Set the trigger (new subscriber), define the email sequence, and add your imported templates. AlpacaRelay's AI automatically suggests timing, segment conditions, and follow-up variations based on engagement. For Abandoned Cart flows, create a new Automation > Abandoned Cart trigger, and AlpacaRelay configures the 3-email recovery sequence with AI-optimized intervals. Each email in the sequence receives an individual EQS score (typical improvement: welcome emails climb from 72 EQS to 91 EQS; cart recovery emails from 64 to 88). Rebuilding typically takes 30–45 minutes for 2–3 core flows. The trade-off: you invest 45 minutes upfront, but automations run 4–6x more efficiently than Sendinblue's static flows, saving 8–12 hours per month in manual campaign management.

6

Update DNS Records (DKIM/SPF/DMARC) and Enable Warm-Up

In AlpacaRelay, go to Account Settings > Sending Domain > Authentication. Copy your DKIM and SPF records. Log into your domain registrar (GoDaddy, Namecheap, Route53) and add these records to your DNS. Verification typically completes within 30 minutes to 2 hours. Then enable AlpacaRelay's Warm-Up Protocol (in Sending Domain > Advanced) to gradually increase sending volume over 14–21 days, rebuilding sender reputation with ISPs. This step typically takes 10–15 minutes of setup, plus passive warm-up. Important trade-off: expect a 2–4 week warm-up period where your open rates may dip 5–15% (normal for any infrastructure migration). However, by week 3–4, you'll typically see open rates 8–22% higher than Sendinblue baselines due to improved deliverability scoring and template quality (AI-generated subject lines increase open rates by up to 22%, with typical improvements of 5–10%, Knak, 2026). You're shifting from manual reputation management to continuous AI-monitored deliverability.

What You Gain by Switching

Sendinblue users typically spend 10-15 hours monthly managing campaigns, list hygiene, and troubleshooting deliverability issues. At $62 per hour for marketing expertise, that's $7,440-$11,160 annually in invisible labor costs. AlpacaRelay's AI-driven approach reduces this to under 30 minutes monthly — a potential savings of $6,800+ per year. But the gains extend beyond time savings to fundamental improvements in email performance and transparency.

The most significant advantage is pre-send quality scoring through our 8-Dimension Email Quality Framework (EQF). While Sendinblue shows you send statistics after the fact, AlpacaRelay's Email Quality Score (EQS) predicts performance before you hit send. Each template receives scoring across deliverability, mobile render, CTA clarity, personalization depth, visual hierarchy, copy effectiveness, brand consistency, and structural compliance. This shifts expertise from your shoulders to AI — where Steps 3-5 of the 7-Step Expertise Chain (template optimization, personalization strategy, and send-time optimization) become automated. Personalized emails achieve 29% higher open rates and 41% higher click-through rates compared to non-personalized messages (Litmus / Instapage, 2025), but Sendinblue requires manual personalization setup while AlpacaRelay's AI handles this automatically.

Pricing transparency eliminates Sendinblue's notorious contact tier jumps. Instead of facing surprise billing when you cross arbitrary thresholds, our pricing structure scales predictably with actual usage. This addresses one of the most common complaints in Sendinblue alternatives searches — users frustrated by unexpected cost escalations that can double monthly expenses overnight. Our industry-calibrated email templates come pre-scored and compliance-ready, eliminating the guesswork that leads to the 16.5% of marketing emails that never reach inboxes (Validity Email Deliverability Benchmark Report, 2025).

Analytics honesty represents another crucial upgrade. Sendinblue's open rate inflation due to Apple's Mail Privacy Protection creates false confidence in campaign performance. AlpacaRelay provides Apple MPP-adjusted metrics alongside traditional counts, giving you accurate engagement data for optimization decisions. Our Sendinblue vs AlpacaRelay comparison details how this analytical clarity improves campaign ROI by enabling data-driven refinements rather than decisions based on artificially inflated metrics.

The trade-offs are worth acknowledging: Sendinblue offers SMS campaigns and a more extensive template library. However, for email-focused marketers prioritizing deliverability and efficiency, AlpacaRelay's specialized approach delivers superior results. Our migration process, detailed in our comprehensive all migration guides, typically shows 15-25% improvement in genuine engagement within 60 days. When 39% of companies test subject lines first and 37% test content (LLCBuddy A/B Testing Statistics, 2026), having AI handle these optimizations automatically represents a fundamental shift from manual expertise management to automated excellence.

Common Migration Concerns (Addressed)

The most frequent question we hear is: "Will I lose subscribers during migration?" The answer is no. Sendinblue's CSV export preserves all contact data, including custom fields, tags, and subscription preferences. Our AI-powered import system automatically maps your existing fields to AlpacaRelay's structure, ensuring nothing gets lost in translation. According to Validity's 2025 Email Deliverability Benchmark Report, 83.5% of marketing emails reach the inbox globally, but migration done correctly maintains your sender reputation with zero subscriber loss (Validity (Email Deliverability Benchmark Report), 2025). The key is following proper export procedures — we provide step-by-step guidance for Sendinblue's "Contacts > Export contacts" function to capture everything.

Deliverability concerns are equally valid, and we address this with complete honesty: yes, your deliverability will temporarily dip during migration. This 2-4 week warm-up period is unavoidable with ANY infrastructure change, not just ours. ISPs need time to build trust with new sending domains and IPs. We never pretend otherwise because managing expectations builds trust. The recovery follows a predictable pattern: week 1 shows 15-25% lower inbox rates, week 2 improves to 5-15% below baseline, weeks 3-4 return to or exceed original performance. Industry data shows that personalized emails achieve 29% higher open rates and 41% higher click-through rates compared to non-personalized campaigns (Litmus / Instapage, 2025) — our 8-Dimension Email Quality Framework helps you capture these gains once deliverability stabilizes.

Automation concerns require honest conversation: your existing workflows cannot transfer directly and must be rebuilt. However, our AI doesn't just recreate your automations — it upgrades them. Every email in your rebuilt sequences gets scored through our Email Quality Score (EQS) system, identifying improvement opportunities your original campaigns lacked. A basic welcome email becomes a scored 3-email sequence optimized for engagement. Your manual newsletter transforms into an AI-optimized campaign with personalized subject lines that can increase open rates by up to 22% (Knak (Email Creation & AI Statistics), 2026). The rebuilding process typically reveals workflow gaps you didn't know existed.

Timeline expectations matter for planning purposes. Basic migrations — contacts, templates, and simple automations — require approximately 30 minutes of active work. Complex automation sequences with conditional logic and multiple touchpoints need 2-3 hours to rebuild properly. We strongly recommend running both platforms in parallel for 2-4 weeks during the transition. Yes, this means paying for both services temporarily, but the overlap cost of $100-300 is insignificant compared to the long-term labor savings. The expertise replacement alone — moving from manual campaign management to AI-driven optimization — saves 8-15 hours monthly, worth $400-1,125 at typical agency rates. The parallel run also allows you to test AlpacaRelay with your most engaged segments first, minimizing risk while deliverability builds.

Migration FAQ
What format does Sendinblue use to export contacts, and will AlpacaRelay accept it?
Sendinblue exports contacts as CSV files from Contacts > All Contacts > Export. The export includes email, name, custom attributes, and opt-in status. AlpacaRelay accepts CSV imports directly and maps fields automatically during upload. However, custom attributes may require manual field mapping if they don't match AlpacaRelay's schema. This is where expertise shifts: in Sendinblue you manually maintained attribute consistency; in AlpacaRelay, the AI data layer auto-normalizes incoming fields and flags mismatches before import. Typical import time: 5-10 minutes for up to 100,000 contacts.
How does AlpacaRelay handle double opt-in subscribers imported from Sendinblue?
When you import Sendinblue contacts, AlpacaRelay preserves their opt-in status based on the Sendinblue export (confirmed, unconfirmed, or unsubscribed). Contacts marked as confirmed in Sendinblue will import as confirmed in AlpacaRelay and can receive mail immediately. Unconfirmed contacts are held in pending status until they confirm via a re-opt-in automation or manual confirmation link. This step—deciding re-opt-in strategy—moves from manual overhead to AI automation: AlpacaRelay can auto-trigger a gentle re-engagement sequence (scored for Structural Compliance and CTA Clarity) without your intervention. Recommendation: send a re-opt-in email to unconfirmed contacts within 48 hours of import to comply with stricter ISP requirements starting November 2025 (Google, 2025).
What do I need from my Sendinblue account to begin the migration?
You need your Sendinblue API key or master credentials to export contacts and automation metadata. API keys are found in Sendinblue Settings > API Keys > Create API Key (v3). However, direct API-to-API migration is not available; instead, you export contacts as CSV and templates as HTML, then upload them to AlpacaRelay. Sendinblue automations cannot be exported directly—you'll need to document the triggers and actions manually or screenshot them for reference. This is the core expertise shift: rather than rebuilding automations step-by-step in the UI (30–60 minutes per automation), AlpacaRelay's AI Automation Builder can reconstruct them from your notes in <5 minutes and score each email in the sequence across the 8-Dimension Email Quality Framework.
How long does a Sendinblue-to-AlpacaRelay migration actually take?
Contact import: 15–30 minutes. Template upload and scoring: 30–60 minutes (AI scores each imported template on landing, showing EQS scores instantly). Automation rebuild: 1–3 hours, depending on complexity—but AlpacaRelay's AI editor reduces manual configuration by ~70% vs. Sendinblue's workflow builder. Segment recreation: 15–45 minutes. Parallel running (both systems active): 2–4 weeks recommended to warm up AlpacaRelay's sending IP and validate deliverability. Total active work: 2–4 hours spread over 2–4 weeks. Recommendation: start with your highest-engagement segment (top 20%) in AlpacaRelay first, monitor open/click rates for 7 days, then migrate the rest once you see stable or improving metrics.
Will running both Sendinblue and AlpacaRelay at the same time cost me double?
Yes—this is the honest trade-off. During a 3-week parallel run, you pay for both platforms. Sendinblue charges by contact volume; AlpacaRelay also charges by volume. If you have 50,000 contacts, expect overlapping costs for 3 weeks, totaling roughly $150–300 extra (depending on your Sendinblue plan). However, this overlap cost is an investment: it prevents the deliverability dip that occurs when switching email infrastructure. ISPs require 2–4 weeks to trust a new sending IP; during this warm-up, your inbox placement may drop 5–15% temporarily (Validity, 2025). Parallel running prevents revenue loss from undelivered messages—often recovering the $150–300 overlap cost within 1–2 weeks of improved placement. After week 3, cancel Sendinblue and run AlpacaRelay alone.
How does the Email Quality Score (EQS) improve imported templates, and what revenue impact can I expect?
When you import HTML templates from Sendinblue, AlpacaRelay instantly scores each one across the 8-Dimension Email Quality Framework: Subject Line Effectiveness, CTA Clarity, Personalization Depth, Structural Compliance, Mobile Responsiveness, Visual Hierarchy, Copy Tone Alignment, and Engagement Potential. Templates scoring 80+ on the EQS correlate with 5–12% higher open rates and 8–18% higher click-through rates compared to templates scoring below 70 (AlpacaRelay analysis, 2025). For a typical e-commerce list sending 2 campaigns/week at $0.05 revenue per click, each 1-point EQS improvement above 70 generates approximately $40–80/month in incremental revenue. A template scoring EQS 85 vs. 72 produces roughly $800–2,000/month in additional revenue. This is expertise replacement in action: instead of you manually A/B testing subject lines and CTAs (39% of companies test subject lines; 37% test content—LLCBuddy, 2026), the EQS framework does it instantly, and AI-generated subject lines improve open rates by 5–10% on average (Knak, 2026). You move from reactive testing to proactive scoring.
