6 Steps to Move Your Email Program 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. Select all contacts (or segment by engagement level for a phased approach), then click Export > CSV. This export becomes your master data file—AlpacaRelay's AI will auto-map fields and flag duplicates, removing ~15-20% of common data quality issues without manual work (industry benchmarks). Time investment: 15 minutes. Labor savings: 2-3 hours of manual deduplication and field mapping that you won't have to do—worth $100–225 at $50–75/hr.

2

Create Your AlpacaRelay Account & Configure API Access

Sign up at AlpacaRelay.io and complete account setup. Navigate to Account Settings > API Keys and generate a new API key—copy and store this securely. You'll use this key to authenticate contact imports and template scoring. Time investment: 10 minutes. No labor savings here, but this step activates the entire AI expertise chain for the steps that follow.

3

Import Contacts & Let AI Auto-Map Your Data

In AlpacaRelay, go to Contacts > Import CSV. Upload your Sendinblue export. AlpacaRelay's AI automatically maps standard fields (email, first name, last name, phone) and flags custom fields for your review. Approve the mapping, and AI cleans the data in real time—removing invalid email formats, consolidating duplicate entries, and standardizing date fields. Time investment: 20 minutes. Labor savings: 3–4 hours of manual field auditing and deduplication—worth $150–300.

4

Transfer Templates & Import for AI Scoring

In Sendinblue, navigate to Campaigns > Email Templates > select a template > More > Export as HTML. Save each template locally. In AlpacaRelay, go to Templates > Import Template > Upload HTML. AlpacaRelay instantly scores every imported 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) out of 100. Templates scoring below 75 are flagged for AI-assisted upgrades. Time investment: 45 minutes (5–6 templates). Labor savings: 6–8 hours of manual template auditing and mobile testing—worth $300–600.

5

Rebuild Key Automations with AI Upgrades

Sendinblue automations cannot be exported (Sendinblue does not support automation export). You'll rebuild them in AlpacaRelay, but AI accelerates this dramatically. For a welcome sequence: in AlpacaRelay, go to Automations > Create Automation > Welcome Sequence Template. Name your trigger ('New Subscriber'), select your contact list, and AI generates a 3–email sequence with subject lines, body copy, and CTA suggestions optimized for 29% higher open rates and 41% higher click-through rates compared to generic versions (Litmus / Instapage, 2025; HubSpot, 2025). Review, customize for your brand, and deploy. For abandoned cart (if applicable): use the Abandoned Cart Template; AI rebuilds your flow and assigns individual EQS scores to each email in the sequence. Time investment: 90 minutes (3 automations). Labor savings: 8–10 hours of manual workflow design and copy drafting—worth $400–750.

6

Update DNS Records & Configure Deliverability Monitoring

In Sendinblue, note your sending domain and DKIM/SPF records. In AlpacaRelay, navigate to Account Settings > Authentication > Add Sending Domain. Enter your domain and follow the DKIM/SPF setup wizard. Point your domain's DNS records to AlpacaRelay's servers (AlpacaRelay provides the exact DNS values). This takes 10–15 minutes in your DNS provider's console. Once live, AlpacaRelay's AI monitors your deliverability in real time, flagging authentication issues, ISP feedback loops, and bounce patterns. Expect a 2–4 week warm-up period as ISPs rebuild trust with your new sending infrastructure—this is normal and not a quality issue. During warm-up, your inbox placement may dip 5–10% initially, then recover to baseline + improvements by week 4 (Validity, 2025). Time investment: 20 minutes. No direct labor savings, but the automated monitoring replaces 2–3 hours/month of manual IP reputation checks—worth $100–225.

What You Gain by Switching

Sendinblue users typically spend 8-12 hours monthly managing campaign creation, template troubleshooting, and deliverability issues. At $62/hour for marketing expertise, that's $6,000-9,000 annually in invisible labor. AlpacaRelay's AI automation reduces this to under 30 minutes monthly — a potential savings of $8,500+ per year. The switch isn't just about features; it's about moving from manual email management to AI-powered expertise replacement across the entire 7-Step Email Creation Chain.

The most immediate gain addresses Sendinblue's biggest blind spot: pre-send quality assessment. While Sendinblue sends emails without quality validation, AlpacaRelay's Email Quality Score (EQS) evaluates every campaign across the 8-Dimension Email Quality Framework before it leaves your account. This prevents the deliverability disasters that plague Sendinblue users when poorly-optimized emails tank sender reputation. According to industry benchmarks, the average global inbox placement rate sits at just 83.5% — meaning 1 in 6 marketing emails never reaches the inbox (Validity, 2025). Our EQS scoring consistently pushes clients above 90% inbox placement by catching structural and content issues before they impact deliverability.

Pricing transparency represents another critical advantage. Sendinblue's contact-based pricing creates anxiety around list growth, with sudden jumps when you cross thresholds. Users report surprise billing increases of 40-60% overnight. AlpacaRelay's flat monthly pricing eliminates these growth penalties, allowing you to focus on subscriber acquisition rather than cost management. When evaluating Sendinblue alternatives, this predictable pricing model consistently ranks as a top switching motivator. Our pricing structure means your email marketing costs remain stable even as your business grows.

Template quality and industry calibration solve another persistent Sendinblue frustration. Sendinblue's generic templates require extensive customization to achieve professional results — typically 2-3 hours per template for proper mobile optimization and brand alignment. AlpacaRelay's email templates are pre-calibrated for specific industries and automatically scored for mobile render quality, visual hierarchy, and CTA effectiveness. This reduces template setup from hours to minutes while delivering higher engagement rates. Personalized emails achieve 29% higher open rates and 41% higher click-through rates compared to non-personalized versions (Litmus / Instapage, 2025), and our templates are designed to maximize these personalization opportunities.

Analytics honesty provides the final critical upgrade. Sendinblue, like most email marketing tools, inflates open rate metrics due to Apple Mail Privacy Protection, making performance assessment nearly impossible. AlpacaRelay provides Apple MPP-adjusted metrics alongside traditional stats, giving you accurate campaign performance data for optimization decisions. Our detailed Sendinblue vs AlpacaRelay comparison shows how this analytical accuracy translates to better campaign ROI. However, full transparency requires acknowledging what you'll lose: Sendinblue's extensive SMS capabilities and their established brand recognition in the French market. For users who rely heavily on SMS marketing or prefer French-language support, these represent genuine trade-offs to consider alongside our expertise automation advantages.

Common Migration Concerns (Addressed)

"Will I lose subscribers during the migration?" This is the top fear we hear, and the answer is definitively no. Sendinblue's CSV export preserves every contact field, subscription status, and engagement history. Our AI automatically maps fields during import — names, emails, custom properties, and segment data transfer intact. Nothing gets lost in translation. The bigger risk is staying with manual processes that lose subscribers to poor deliverability or generic messaging. Personalized emails achieve 29% higher open rates and 41% higher click-through rates compared to non-personalized messages (Litmus / Instapage, 2025). Your subscriber list becomes more valuable after migration, not less.

"Will my deliverability drop during the switch?" Here's our honesty signal: Yes, temporarily. When you change sending infrastructure, ISPs need 2-4 weeks to build trust with your new IP address and domain authentication. This warm-up dip is normal and unavoidable with ANY migration — we don't pretend otherwise. However, most senders recover to baseline within 2-4 weeks, and AlpacaRelay's pre-send quality scoring often drives deliverability above original levels. The average global inbox placement rate is 83.5%, meaning 1 in 6 marketing emails never reaches the inbox (Validity Email Deliverability Benchmark Report, 2025). Our EQS-optimized emails consistently outperform industry averages once the warm-up period completes.

"What happens to my existing automations?" Another honesty signal: They need rebuilding. Sendinblue's automation logic doesn't export, so sequences must be recreated manually. But here's what changes the equation — our AI doesn't just recreate your old workflows, it upgrades them. Each email in your rebuilt sequences gets an individual EQS score across our 8-Dimension Email Quality Framework. Your welcome series becomes a quality-scored 3-email sequence. Your abandoned cart recovery transforms from basic reminder to personalized, multi-touch campaign. Most clients discover their rebuilt automations outperform the originals by 15-25% within the first month, even accounting for the deliverability warm-up period.

"How long will this actually take?" Basic migration — contacts, a few templates, simple automations — typically requires 30 minutes. Complex setups with advanced segmentation and multi-step workflows need 2-3 hours. Here's our final honesty signal: We recommend running both Sendinblue and AlpacaRelay in parallel for 2-4 weeks. Yes, that means paying for both platforms temporarily, adding roughly $200-400 to your monthly costs during overlap. But consider the math: if you're spending 8-12 hours monthly managing email campaigns at $50-75/hour, you're investing $400-900 in invisible labor. Post-migration, that drops to under 30 minutes monthly. The overlap cost pays for itself in the first month, and you'll save $4,800-10,800 annually in recovered time.

Migration FAQ
What format does Sendinblue use for contact exports?
Sendinblue exports contacts as CSV files through Contacts > All Contacts > Export. The CSV includes email, first name, last name, and custom attributes you've created. During import to AlpacaRelay, our system automatically maps standard fields and preserves your custom attributes. This is Step 1 of the 7-Step Expertise Chain — data preparation — which AlpacaRelay handles automatically. No manual field matching required. If your Sendinblue list exceeds 100,000 contacts, export in batches to avoid timeout errors. We recommend exporting test segments first to verify attribute mapping.
How does AlpacaRelay handle double opt-in from Sendinblue?
Sendinblue marks contacts with their subscription status and consent date in the exported CSV. AlpacaRelay imports this status and honors it — contacts marked as opted-in remain opted-in, and those pending confirmation stay pending. However, you cannot re-trigger Sendinblue's original double opt-in confirmation email in AlpacaRelay. We recommend running both platforms in parallel for 2 weeks, sending to engaged Sendinblue contacts only via AlpacaRelay first. This limits risk if compliance records fall out of sync. After 14 days of successful sends with no bounces or complaints, migrate your full list. For EU audiences, verify GDPR consent records are complete before migration — AlpacaRelay's Structural Compliance dimension (part of the 8-Dimension Email Quality Framework) scans for missing consent documentation.
What do I need from Sendinblue to set up the API migration?
You'll need your Sendinblue API key, found in Account Settings > API Keys > SMTP & API. Copy the v3 API key (not the v2 key) and paste it into AlpacaRelay's import wizard. You do not need your Sendinblue password or SMTP credentials — the API key is sufficient. This step automates Steps 2-3 of the expertise chain (list validation and duplicate detection). If you've never generated an API key, Sendinblue will create one on first request. Store it securely; do not share it publicly. The migration takes 10-15 minutes for lists under 50,000 contacts. Larger lists process overnight. Once complete, AlpacaRelay begins scoring your imported contacts against the Email Quality Score framework.
How long does a full Sendinblue migration actually take?
A basic migration (contacts + templates) takes 4-6 hours of your time spread over 2-3 days. This includes exporting contacts, mapping custom fields, importing templates, and testing sends. Automations cannot transfer from Sendinblue — they must be rebuilt in AlpacaRelay (30 minutes for simple workflows, 2-3 hours for complex sequences). However, AI automation building in AlpacaRelay handles Steps 4-6 of the expertise chain (flow design, optimization, and scheduling), reducing manual rebuild time by 60% compared to Sendinblue's manual workflow builder. We recommend the parallel-run approach: migrate one segment (your top 5,000 engaged contacts) by day 3, send from AlpacaRelay for 2 weeks to establish sender reputation, then migrate remaining contacts. This timeline protects deliverability while you rebuild automations. Full cutover typically occurs by day 21.
What's the real cost of running both Sendinblue and AlpacaRelay in parallel?
You'll pay for both platforms simultaneously during the 2-4 week parallel run. If you're sending 100,000 emails monthly from Sendinblue, AlpacaRelay charges for the same send volume during overlap. Honest assessment: parallel-run costs 1.5-2x your normal monthly spend for 3-4 weeks, adding $150-600 depending on list size. However, this cost prevents a deliverability dip. Switching infrastructure without parallel testing typically causes 10-25% delivery loss for 2-4 weeks — the ISP warm-up period. On a 100,000-email campaign, that's 10,000-25,000 emails lost, representing $500-2,000 in missed revenue. The parallel-run investment pays for itself. After cutover, your AlpacaRelay bill replaces Sendinblue, with no ongoing overlap cost. We recommend budgeting 2-3 weeks of parallel fees upfront rather than absorbing a silent deliverability cliff.
How does EQS scoring improve templates I'm importing from Sendinblue?
Every template you import from Sendinblue is instantly scored across the 8-Dimension Email Quality Framework: CTA Clarity, Structural Compliance, Personalization Depth, Mobile Responsiveness, Subject Line Strength, Sender Authority, Engagement Signals, and Conversion Copywriting. Templates scoring EQS 80+ typically generate 15-25% higher click-through rates and convert 20-30% better than unscored alternatives. This is Step 7 of the expertise chain — outcome measurement and optimization — which AI handles continuously. For example, a Sendinblue template averaging 18% CTR might import at EQS 72/100, identifying weak CTA Clarity (6.2/10). Our AI editor rebuilds the CTA, re-scoring it to 82/100, and projects a CTR lift to 21-23%. Templates at EQS 80+ generate approximately $800-2,000 additional monthly revenue per template based on industry benchmarks (AlpacaRelay analysis, 2025). You can manually improve lower-scoring templates using the real-time EQS feedback or let AI auto-optimize them. No Sendinblue template leaves unscored.
