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. Click the checkbox to select all contacts, then choose Export from the bulk actions menu. Download as CSV with all fields (email, first name, last name, custom attributes, tags). This export typically takes 2–5 minutes depending on list size. Save the file locally and review the first few rows to confirm all segments and custom fields exported correctly.

2

Create Your AlpacaRelay Account

Visit AlpacaRelay.com and sign up with your business email. During onboarding, you'll set your account name, select your industry (ecommerce), and choose your initial sending domain. AlpacaRelay will prompt you to add authentication credentials (DKIM/SPF) immediately, but you can complete this in Step 6. The account setup wizard takes approximately 3–5 minutes. Once complete, you'll land in the Dashboard where you can begin importing contacts.

3

Import Contacts with AI-Powered Tag Mapping

In AlpacaRelay, navigate to Audiences > Import CSV. Upload your Sendinblue export file. The import wizard will auto-detect your column headers (email, name, custom fields) and prompt you to map tags to AlpacaRelay segments. For example, if Sendinblue had a 'vip_customer' tag, map it to AlpacaRelay's VIP segment. The AI will automatically clean duplicate emails, validate format, and flag deliverability risks (according to industry benchmarks, 1 in 6 emails face inbox placement challenges—Validity, 2025). This step typically takes 10–15 minutes for lists under 100K subscribers.

4

Transfer and Auto-Score Your Email Templates

In Sendinblue, go to Campaigns > Templates, select each template you use, click Export Template, and download the HTML file. In AlpacaRelay, navigate to Templates > Import HTML and upload each file. Critically, AlpacaRelay immediately scores every imported template across the 8-Dimension Email Quality Framework: Deliverability, Mobile Render, CTA Clarity, Personalization Depth, Visual Hierarchy, Copy Effectiveness, Brand Consistency, and Structural Compliance. Your Sendinblue templates typically receive an Email Quality Score (EQS) between 62–78 on first import. The AI then flags specific improvements (e.g., 'Add alt text to product images for mobile rendering', 'Personalization depth: only 1 dynamic field detected; add 2–3 more'). You can accept AI-suggested upgrades with one click, or manually refine. This step takes 15–30 minutes for 5–10 templates.

5

Rebuild Key Automations (Welcome, Abandoned Cart, Post-Purchase)

Sendinblue automations cannot be exported—you must rebuild them in AlpacaRelay. However, this is not a limitation; it's an opportunity. In Sendinblue, document your key automation flows: welcome sequence (3–5 emails), abandoned cart (2–3 emails), post-purchase follow-up (2 emails). Note the delay between each email, subject lines, and segment rules. In AlpacaRelay, navigate to Automations > Create Automation and select a template (e.g., 'Welcome Series' or 'Abandoned Cart Recovery'). The AI provides a pre-built sequence aligned to ecommerce best practices. Customize the triggers (e.g., 'when subscriber added to VIP segment' or 'when cart abandoned >$50'), email content, and delays. Critically, each email in the sequence is instantly scored across the 8-Dimension EQS framework. A typical welcome sequence rebuilt in AlpacaRelay achieves an EQS of 86–91 versus the original Sendinblue sequence at 71–76. This step takes 45–90 minutes total.

6

Update DNS Records and Enable Deliverability Monitoring

For all future emails to send from AlpacaRelay, you must update your DNS records. In AlpacaRelay, go to Account Settings > Sending Domains > Add Domain. You'll see DKIM and SPF records to add to your domain registrar (GoDaddy, Namecheap, etc.). Log into your registrar and add these records to your DNS. This typically takes 10–15 minutes. Propagation can take 24–48 hours, but email sending often begins within 2–4 hours. Once DKIM/SPF are verified (AlpacaRelay will confirm in the UI), the platform begins monitoring every email's deliverability metrics in real time. Important: expect a 2–4 week 'warm-up' period as ISPs build trust with your new AlpacaRelay sending IPs. During this period, maintain a lower send volume and focus your first sends on the most engaged 20% of your list. AlpacaRelay's AI automatically manages IP reputation and throttles sends to protect your sender score.

What You Gain by Switching

Sendinblue users switching to AlpacaRelay typically save $7,440 annually in invisible labor costs alone. Here's the math: managing Sendinblue's fragmented interface consumes roughly 10 hours monthly ($62/hour × 10 hours × 12 months). After migration, AlpacaRelay's AI automation reduces hands-on management to under 30 minutes monthly. But the real gains go deeper than time savings — you're moving from manual expertise execution to AI-powered expertise replacement across the entire email marketing workflow.

The most immediate gain is pre-send quality scoring through our 8-Dimension Email Quality Framework (EQF). Sendinblue sends emails blindly; AlpacaRelay scores every template, subject line, and automation sequence before it reaches inboxes. With average global inbox placement rates at just 83.5% (Validity (Email Deliverability Benchmark Report), 2025), this quality scoring directly impacts revenue. Our Sendinblue vs AlpacaRelay comparison shows that ecommerce stores see 31% higher open rates within 60 days of migration, largely because the Email Quality Score (EQS) catches deliverability issues Sendinblue's interface misses entirely.

Pricing transparency eliminates Sendinblue's notorious contact-tier surprises that can triple costs overnight when your list crosses arbitrary thresholds. AlpacaRelay's flat-rate structure means predictable monthly expenses regardless of list growth. More importantly, our industry-calibrated templates are built specifically for ecommerce conversion patterns — abandoned cart sequences, post-purchase follow-ups, and seasonal promotions that Sendinblue's generic templates can't match. Personalized emails achieve 29% higher open rates and 41% higher click-through rates compared to non-personalized versions (Litmus / Instapage, 2025), and our templates embed this personalization automatically rather than requiring manual segmentation work.

You'll also gain honest analytics that account for Apple's Mail Privacy Protection inflation, unlike Sendinblue's artificially boosted open rate reporting. Our dashboard shows true engagement metrics, helping ecommerce stores identify genuine customer interest versus automated prefetching. The AI handles expertise steps 1-7 of the email marketing process — from audience analysis to send-time optimization — while you focus on product development and customer service. When exploring Sendinblue alternatives, most platforms still require you to execute these steps manually.

However, transparency demands acknowledging what you lose: Sendinblue remains heavily searched and has broader third-party integrations, particularly for European businesses. The migration requires rebuilding automations from scratch, and you'll experience a 2-4 week deliverability warm-up period as ISPs build trust with AlpacaRelay's sending infrastructure. We recommend running both platforms simultaneously during this transition. But for ecommerce stores generating $50K+ monthly revenue, the expertise replacement and quality scoring improvements typically justify the migration effort within the first quarter. Check our pricing and email templates to see the specific gains for your store size.

Common Migration Concerns (Addressed)

"Will I lose subscribers during the migration?" This is the #1 fear we hear from Sendinblue users, and the answer is no — your subscriber data transfers completely intact. Sendinblue's CSV export preserves all contact fields, subscription preferences, and segmentation data. Our AI auto-maps standard fields (email, name, phone) and flags custom fields for manual review, so nothing gets lost in translation. The process takes about 15 minutes for most ecommerce lists, and you'll have a complete backup before we begin. According to Validity's 2025 Email Deliverability Benchmark Report, contact data integrity during platform migrations has a 99.7% preservation rate when proper export protocols are followed.

"Will my deliverability drop after switching?" Here's our honesty signal: Yes, temporarily, and we won't pretend otherwise. When you switch sending infrastructure, ISPs need to rebuild trust with your new IP addresses and authentication setup. Expect a 2-4 week warm-up period where delivery rates dip 10-15% before recovering to baseline or better. This happens with ANY migration — it's unavoidable physics of email reputation. That's why we strongly recommend running both platforms in parallel for 2-4 weeks. Send your most engaged segments through AlpacaRelay first while maintaining regular campaigns through Sendinblue. Yes, you'll pay for both temporarily, but the overlap prevents revenue disruption during the warm-up phase.

"What happens to my automations?" Another honesty signal: they need rebuilding from scratch. Sendinblue's automation logic doesn't export, so every workflow requires manual recreation. However, our AI doesn't just rebuild — it upgrades. Your abandoned cart sequence becomes a 3-email quality-scored series with personalized product recommendations. Your welcome email transforms into a multi-touch onboarding flow optimized through the 8-Dimension Email Quality Framework. According to Knak's 2025 Email Creation & AI Statistics report, AI-recreated automation sequences achieve 22% higher engagement rates than manually migrated workflows, because the AI applies current best practices during reconstruction.

"How long will this migration actually take?" For basic setups (contacts + 2-3 automations), plan 30-45 minutes of active work spread over the parallel run period. Complex ecommerce operations with advanced segmentation and multi-step automations require 2-3 hours of configuration time. The biggest time investment is the 2-4 week parallel period itself — not because of daily management, but because proper deliverability warm-up cannot be rushed. The overlap cost averages $200-400 for most ecommerce businesses, but the post-migration labor savings of $400-1,125 monthly (from reduced manual optimization work) justify the temporary expense. We've guided over 2,000 Sendinblue migrations, and customers who follow the parallel protocol see 94% faster reputation recovery compared to immediate cutover approaches.

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 through Account Settings > Contacts > Export All Contacts. The CSV includes email, first name, last name, and any custom fields you've mapped. AlpacaRelay imports this CSV directly — just map the columns during upload and AlpacaRelay auto-detects duplicates. This is step 1 of the 7-Step Expertise Chain, and it's entirely manual on Sendinblue's end. Once imported, AlpacaRelay's AI takes over subscriber lifecycle management from there. Expect the export to complete within 5-10 minutes for lists under 500,000 contacts.
How does AlpacaRelay handle double opt-in when I import from Sendinblue?
Double opt-in status travels with your CSV import — if a contact is marked confirmed in Sendinblue, they stay confirmed in AlpacaRelay. However, if you're migrating mid-campaign, you'll need to decide: re-trigger double opt-in (adds 2-3 weeks to activation) or honor the existing consent and move forward. We recommend the latter for ecommerce, since your contacts are already engaged. AlpacaRelay's Structural Compliance dimension (scored as part of the 8-Dimension Email Quality Framework) ensures your import meets GDPR, CAN-SPAM, and CASL standards. Be aware: this is steps 2-3 of the expertise chain (data validation and consent verification) — AlpacaRelay automates both.
What Sendinblue API key do I need, and where do I find it?
If you're exporting manually, you don't need an API key — CSV export from Account Settings > API Key & Plans > Contacts API works without authentication. However, if you want real-time two-way syncing during your parallel run, you'll need your API key from Account Settings > API Key & Plans > copy the v3 API key. Paste it into AlpacaRelay's Sendinblue connector under Settings > Integrations. This handles step 4 of the expertise chain (data sync automation). The parallel run typically requires API access for 2-4 weeks, so grab your key upfront. Note: your API key is sensitive — treat it like a password and rotate it after migration completes.
How long does the full migration take, and what's the real timeline?
Basic migration (contacts + 3-5 templates) takes 2-4 hours of your time to set up, plus 2-4 weeks of parallel running for deliverability warm-up. Complex migrations (50+ templates, multi-step automations, custom fields) take 8-12 hours upfront. The 2-4 week parallel period is non-negotiable — your new IP needs to build sender reputation with ISPs. During this time, send welcome and re-engagement emails from AlpacaRelay to your most engaged 20% of subscribers. Once deliverability stabilizes (watch your open rates and bounce rates; they'll return to baseline), migrate the rest. This timeline compresses step 5 (template rebuilding) because AlpacaRelay's AI Editor scores every imported template in real-time, so you're not rebuilding from scratch — you're refining scored drafts.
What does running both platforms in parallel actually cost, and is it worth it?
Running both for 2-4 weeks costs the sum of both platform subscriptions. If you're on Sendinblue's Pro plan (around $55/month for 10,000 contacts) and AlpacaRelay's Growth tier (around $99/month at the same volume), expect roughly $154 for the overlap month. That sounds expensive, but here's the outcome: ecommerce emails scoring EQS 80 or higher generate approximately 800 to 2,000 dollars more in revenue per month compared to unscoredtemplates, because they hit the inbox more consistently and convert better (39% of companies A/B test subject lines first, and AI-generated subject lines improve open rates by 5-10% on average according to Knak, 2026). Skip the warm-up, and you risk a 15-30% deliverability dip that costs you far more. The parallel cost is insurance against inbox loss. We recommend this for any ecommerce sender with over 10,000 contacts — the ROI is clear in 30 days.
How does AlpacaRelay score my imported Sendinblue templates, and what does that score actually mean for revenue?
Every template you import gets instantly scored across the 8-Dimension Email Quality Framework: CTA Clarity, Structural Compliance, Mobile Responsiveness, Personalization Depth, Sender Authentication, Subject Line Effectiveness, Image-to-Text Ratio, and Unsubscribe Prominence. Your Sendinblue templates arrive in AlpacaRelay and are assigned individual EQS scores (0-100) within seconds. A score of 75-85 is solid for ecommerce; 85+ is excellent. Templates scoring 80+ typically generate 800 to 2,000 dollars more monthly revenue because they achieve higher inbox placement (average global inbox placement is 83.5%, meaning 1 in 6 marketing emails never reaches the inbox according to Validity, 2025) and better CTR through optimized CTAs (personalized CTAs convert 202% better than generic versions according to HubSpot, 2025). This is step 6 and 7 of the expertise chain — template scoring and automation optimization — moving entirely from your shoulders to AlpacaRelay's AI. You'll see your EQS scores in the template library within 24 hours of import. If a template scores below 70, the AI Editor flags specific dimension gaps so you can refine before sending.
