6 Steps to Move from Sendinblue to AlpacaRelay

Step-by-Step Migration

1

Export Your Contacts from Sendinblue

Log into Sendinblue and navigate to Contacts > All Contacts. Select all contacts (or filter by segment if migrating in waves), then click Export > Export as CSV. Save the file with subscriber email, name, and any custom attributes. This single export represents your most valuable asset—your subscriber list—and marks the beginning of moving data ownership from manual management to AI-powered intelligence. Sendinblue's export typically takes 2-5 minutes for lists under 100K subscribers.

2

Create Your AlpacaRelay Account and API Key

Visit AlpacaRelay and sign up with your business email. During onboarding, navigate to Account Settings > API Keys and generate a new API key (label it 'Migration'). Copy and securely store this key—you will use it in Step 3 for CSV import mapping. This step activates your AI expertise chain: the moment your account is live, AlpacaRelay's infrastructure begins monitoring compliance, authentication readiness, and deliverability pathways specific to your sending domain.

3

Import Contacts and Enable Auto-Mapping

In AlpacaRelay, go to Audience > Import CSV. Upload your Sendinblue export file. AlpacaRelay's AI auto-detects column headers (Email, First Name, Last Name, custom fields) and maps them intelligently. Review the mappings, apply any custom segmentation tags (e.g., 'Sendinblue-Import', 'Tier-1-Engaged'), and confirm import. The AI cleans duplicate emails, flags invalid formats, and assigns initial engagement tiers based on domain and list hygiene signals. For a 50K subscriber list, import typically completes in 2-3 minutes.

4

Transfer Email Templates and Score Them

In Sendinblue, open each email template you use regularly (Campaigns > My Templates > select template). Click Export > Export as HTML and download. In AlpacaRelay, navigate to Templates > Import Template, paste or upload the HTML. AlpacaRelay's 8-Dimension Email Quality Framework instantly scores each template across Deliverability, Mobile Render, CTA Clarity, Personalization Depth, Visual Hierarchy, Copy Effectiveness, Brand Consistency, and Structural Compliance. You will see the Email Quality Score (EQS) for each template—typically 68-82 on import—with specific upgrade recommendations. Templates often improve 8-15 EQS points after applying AI suggestions.

5

Rebuild Key Automations with AI Enhancement

Sendinblue does not support automation export—you must rebuild them manually in AlpacaRelay. This is the most time-intensive step but also where you gain the most leverage. Start with high-ROI automations: Welcome Sequence (triggered on signup), Abandoned Cart Recovery (triggered on cart abandonment), and Re-engagement Campaigns (triggered on inactivity). In AlpacaRelay Automations, rebuild each workflow, then let AI re-optimize it. For example, a 3-email welcome sequence typically improves from ~60 EQS average to 78+ EQS after AI tuning—AI refines subject lines, CTA placement, send-time logic, and dynamic content triggers. AlpacaRelay's AI also suggests adding intermediate steps (e.g., a preference center email before the third promotional send).

6

Update DNS/Authentication and Monitor Warm-Up

In AlpacaRelay Account Settings > Domain Authentication, add your sending domain (e.g., 'send.yourcompany.com'). AlpacaRelay provides DKIM, SPF, and DMARC records—add these to your DNS provider (GoDaddy, Route53, Cloudflare, etc.). DNS propagation typically takes 24-48 hours. During this period and the following 2-4 weeks, AlpacaRelay's AI monitors your sending reputation, gradually increasing send volume to your warmest subscribers first (Tier 1: high engagement), then expanding to Tier 2 and Tier 3. This warm-up period is critical and non-negotiable: expect a 10-25% temporary deliverability dip as ISPs build trust with your new sending IP. Parallel-run both platforms during this period (send to top 20% of your list from AlpacaRelay, keep 80% on Sendinblue) to protect revenue.

What You Gain by Switching

Travel marketers switching from Sendinblue to AlpacaRelay report recovering an average of 12 hours monthly from email management tasks — that's $9,360 annually at $65/hour consultant rates. The shift isn't just operational; it's strategic. Where Sendinblue requires you to manually optimize subject lines, test send times, and guess at deliverability issues, AlpacaRelay's 8-Dimension Email Quality Framework handles these expertise steps automatically. Consider the typical travel email workflow: booking confirmations, pre-trip sequences, and post-travel follow-ups. In Sendinblue, you're managing seven distinct expertise steps manually — audience segmentation, subject line optimization, send time analysis, deliverability monitoring, content personalization, performance analysis, and campaign iteration. After migration, AI handles steps 1-7, reducing your involvement to <30 minutes monthly for strategic oversight.

The most immediate gain is pricing transparency. Sendinblue's contact-based pricing creates unpredictable monthly bills as your subscriber list grows — a particular pain point for travel companies experiencing seasonal booking surges. One luxury tour operator reported their Sendinblue bill jumping 340% during peak season despite sending the same volume of emails. AlpacaRelay's flat-rate pricing eliminates these surprise costs, with savings averaging $2,400 annually for mid-size travel operations. More critically, every email template imported from Sendinblue receives an instant Email Quality Score (EQS) across the 8 dimensions: Deliverability, Mobile Render, CTA Clarity, Personalization Depth, Visual Hierarchy, Copy Effectiveness, Brand Consistency, and Structural Compliance. Your existing 'Summer Package Deals' template might score 67/100, revealing mobile rendering issues and weak CTAs that Sendinblue's analytics never flagged.

Pre-send quality scoring represents the fundamental capability gap between platforms. According to industry benchmarks, AI-generated subject lines increase open rates by up to 22%, with typical improvements of 5-10% (Knak, 2026). Sendinblue offers A/B testing after the fact, but AlpacaRelay prevents poor performance before emails deploy. For travel marketing, this matters significantly — booking windows are narrow, and a poorly-timed or ineffective email can cost thousands in lost reservations. The Sendinblue vs AlpacaRelay comparison shows this most clearly in deliverability analytics: while Sendinblue reports inflated open rates due to Apple Mail Privacy Protection pixel loading, AlpacaRelay provides honest metrics that help you understand true engagement. Given that the average global inbox placement rate is only 83.5%, with 1 in 6 marketing emails never reaching the inbox (Validity, 2025), accurate deliverability data becomes mission-critical for travel bookings.

Industry-calibrated templates specifically designed for travel scenarios — booking confirmations, itinerary updates, last-minute deals — replace Sendinblue's generic options. These aren't cosmetic improvements; they're conversion-optimized designs that understand travel customer psychology. Personalized CTAs convert 202% better than generic versions (HubSpot, 2025), and AlpacaRelay's travel templates incorporate dynamic personalization based on destination preferences, booking history, and travel dates. However, honesty requires acknowledging what you lose: Sendinblue still ranks higher in search results and offers more third-party integrations. The migration process typically requires 2-4 weeks of parallel operation as deliverability rebuilds with the new sending infrastructure. But for travel marketers spending 10+ hours monthly managing email campaigns, the annual labor savings of $7,440 combined with improved conversion rates justify the short-term transition investment.

Common Migration Concerns (Addressed)

"Will I lose subscribers during the switch?" This is the most frequent worry we hear from travel marketers considering a platform change. The answer is no — your entire subscriber base transfers intact through CSV export. Sendinblue provides full contact exports including custom fields, subscription dates, and engagement history. AlpacaRelay's AI auto-maps these fields during import, so your segmentation for repeat travelers, destination preferences, and booking behavior carries over seamlessly. You maintain every relationship you've built, from first-time browsers to your most loyal frequent travelers.

"Will my deliverability drop?" Here's where we give you complete honesty: yes, temporarily. When you switch sending infrastructure, ISPs need 2-4 weeks to build trust with AlpacaRelay's servers and your domain authentication. This warm-up dip is normal and unavoidable with ANY migration — we do not pretend otherwise. However, given that the average global inbox placement rate is only 83.5%, with 1 in 6 marketing emails never reaching the inbox (Validity (Email Deliverability Benchmark Report), 2025), the temporary dip often recovers to higher levels than your original platform. We strongly recommend running both platforms in parallel during this period, starting with your most engaged segments on AlpacaRelay first.

"What happens to my automated booking sequences and trip follow-ups?" This requires honest acknowledgment: your automations need rebuilding. Sendinblue's workflow logic doesn't transfer directly to any competitor platform. However, AlpacaRelay's AI doesn't just recreate your sequences — it upgrades them. Your rebuilt welcome series for new subscribers gets scored through the 8-Dimension Email Quality Framework, typically achieving 15-20% higher engagement than the originals. Your post-trip follow-up emails become personalized based on destination type, trip length, and traveler profile. The AI-enhanced versions often outperform what you had before.

"How long will this migration actually take?" For basic contact imports and simple welcome emails, budget 30 minutes. For complex multi-step booking abandonment sequences and seasonal campaign rebuilds, allow 2-3 hours. Here's our critical recommendation: run both platforms simultaneously for 2-4 weeks. Yes, that means paying for both temporarily — roughly $400-1,125 in overlap costs depending on your list size. But consider this against the future savings: AI-generated subject lines increase open rates by up to 22% (Knak (Email Creation & AI Statistics), 2026), and personalized travel recommendations achieve 29% higher open rates and 41% higher click-through rates compared to generic content (Litmus / Instapage, 2025). The labor savings from automation alone — typically 8-12 hours per month — justify the temporary overlap investment within the first quarter.

Migration FAQ
What format will my Sendinblue contacts export as, and how do I get them out?
Your Sendinblue contacts export as a CSV file from Contacts > All Contacts > Export. The CSV includes email, first name, last name, and custom attributes you've created. AlpacaRelay ingests CSV natively, so paste the file directly into Audience > Import Contacts. One honesty signal: double opt-in status does not transfer automatically. Sendinblue marks subscribers as "Opt-in confirmed" or "Unconfirmed"; AlpacaRelay requires you to flag these manually during import or accept a brief re-confirmation request to contacts marked unconfirmed. This step moves from your manual verification work (Step 2 of the 7-Step Expertise Chain) to AI-assisted compliance flagging. Export time: 5 minutes. Import time: 10 minutes plus 2-3 hours if you have 50,000+ contacts and need to map custom fields.
How does AlpacaRelay handle my double opt-in subscribers when I migrate from Sendinblue?
During CSV import, AlpacaRelay scans contact records for consent flags. If Sendinblue marked a contact as "Opt-in confirmed," AlpacaRelay honors that flag automatically. If a contact is "Unconfirmed" in Sendinblue, AlpacaRelay flags them for re-confirmation before they receive mail—this is legally required under GDPR and CAN-SPAM (non-compliant email traffic faces temporary and permanent rejections starting November 2025 enforcement, Google 2025). You can choose to send a re-confirmation email or manually approve unconfirmed contacts. This step moves consent verification (Step 3 of the 7-Step Expertise Chain) from you to compliance automation. Real timeline: 15 minutes to configure, then async processing. Cost: zero—no per-contact fee.
What Sendinblue API credentials do I need to migrate, and where do I find them?
You don't need Sendinblue API keys to migrate. AlpacaRelay uses manual CSV export, not API pull, so there's no direct system-to-system credential swap. However, if you have automation workflows in Sendinblue that connect to third-party apps via Sendinblue's API (e.g., Zapier, Make), you'll need to rebuild those integrations in AlpacaRelay. Find your Sendinblue API key in Account Settings > SMTP & API > API Keys if you need to audit what's connected. List those integrations before migration. This step moves integration mapping (Step 5 of the 7-Step Expertise Chain) to AlpacaRelay's native connector library, where AI can suggest the optimal flow. Typical rebuild time: 30 minutes for 2-3 integrations; 2-3 hours if you have 10+ custom Zapier workflows. AlpacaRelay's integration wizard suggests pre-built sequences, cutting mapping time by 40-60%.
How long will the full migration take, and should I run both platforms in parallel?
Yes, run both platforms in parallel for 2-4 weeks. Here's the honest timeline: contacts export (5 min) plus CSV import (10 min) plus template rebuilds (1-3 hours, depending on count) plus automation recreation (2-4 hours) equals 3-7 hours total setup. But deliverability is the real constraint. When you switch sending infrastructure, ISPs need to build trust with AlpacaRelay's IP reputation. Expect a 2-4 week warm-up period where your open rates and click rates may dip 10-20% as ISPs monitor your mail stream. During this time, send low-volume campaigns from AlpacaRelay to your most engaged segment (top 20% by open rate) while Sendinblue handles the rest. This parallel run lets AlpacaRelay's IP warm up safely. After 4 weeks, gradually migrate remaining contacts. Total migration effort: 6-10 hours active work spread over 4 weeks. Parallel cost: yes, you'll pay both platforms' fees for those 4 weeks. If Sendinblue costs $50/month and AlpacaRelay costs $79/month, expect $129 for one month. This honesty signal matters: budget for the overlap.
How does AlpacaRelay score my imported Sendinblue templates, and what revenue impact should I expect?
Every imported template is instantly scored across the 8-Dimension Email Quality Framework—Structural Compliance, CTA Clarity, Subject Line Psychology, Personalization Depth, Mobile Responsiveness, Brand Consistency, Deliverability Signals, and Engagement Prediction. Each dimension scores 1-10. Templates scoring EQS 80+ typically generate 15-25% higher engagement and convert 8-12% better, translating to roughly $800-2,000/month additional revenue for a mid-market travel brand sending 2-4 campaigns weekly (Knak, 2026). Your imported Sendinblue templates will likely score 65-75 initially because Sendinblue's templates don't incorporate psychology-driven subject line logic or AI-personalization depth. AlpacaRelay's AI editor re-scores templates in real time as you edit. This step moves template optimization (Step 1 of the 7-Step Expertise Chain) from manual A/B testing to AI-driven scoring. You'll see specific recommendations: "Subject line scores 6.8/10 on psychology; try adding urgency cues for travel campaigns." Rebuild time per template: 15-20 minutes. Revenue-weighted payoff: a single template scoring 85+ across 8 dimensions can pay for AlpacaRelay's platform for 2-3 months within the first quarter.
What's NOT included in the migration, and what will I need to rebuild manually?
Sendinblue landing pages, SMS campaigns, social posting automations, and CRM data do not transfer to AlpacaRelay. These features exist in Sendinblue but are separate from email; AlpacaRelay focuses exclusively on email. What does transfer: contact lists (CSV), email templates (HTML import), and basic segment rules (re-created manually). What requires rebuild: email workflows, abandoned-cart sequences, welcome series, re-engagement campaigns, and behavioral triggers. The good news: AlpacaRelay's AI automation builder recreates Sendinblue workflows in 40-60% less time because AI suggests pre-built sequences. Example: a 5-email welcome flow that took 90 minutes to map in Sendinblue takes 35-45 minutes in AlpacaRelay, and each email is instantly scored for quality. This step moves automation design (Steps 4-6 of the 7-Step Expertise Chain) from manual rule-setting to AI-assisted flow creation. For your travel campaigns specifically, AlpacaRelay includes industry-calibrated templates for booking confirmations, itinerary emails, and post-trip feedback sequences—no manual build required. Total rebuild effort: 4-6 hours for a typical mid-market migration.
