Export Sender Contacts and Data

Step-by-Step Migration

1

Export Your Contacts from Sender

Log into your Sender account and navigate to Contacts > All Contacts. Click the Export button in the top-right corner and select CSV format. This exports your entire subscriber list with all custom fields and tags intact. You'll receive a .csv file containing email addresses, names, subscription status, and any custom attributes you've tracked.

2

Create Your AlpacaRelay Account and Configure Workspace

Sign up for AlpacaRelay at alpacarelay.com. During onboarding, you'll name your workspace, set your timezone, and configure your primary sender email address. Complete the setup wizard, which takes 8-12 minutes. Then, generate your API key in Account Settings > API Keys — copy and save this key securely; you'll need it in later steps.

3

Import Contacts via CSV Upload with AI Auto-Mapping

In AlpacaRelay, go to Contacts > Import > CSV Upload. Drag and drop your exported Sender CSV file. The AI will automatically map your columns to AlpacaRelay fields (email, first name, custom attributes). Review the mapping preview; if any fields are misaligned, correct them manually. Click Confirm, and AlpacaRelay will ingest and clean your data within 2-5 minutes.

4

Transfer and Score Your Email Templates

In Sender, navigate to Templates > select a template > click Export HTML. Save the file. In AlpacaRelay, go to Templates > Import > Upload HTML. Paste or upload each template. AlpacaRelay will instantly score every template across the 8-Dimension Email Quality Framework (Deliverability, Mobile Render, CTA Clarity, Personalization Depth, Visual Hierarchy, Copy Effectiveness, Brand Consistency, Structural Compliance), generating an Email Quality Score (EQS) out of 100.

5

Rebuild Key Automations with AI Enhancements

Sender does not support automation export — you must rebuild automations in AlpacaRelay manually, but AI accelerates the process. In AlpacaRelay, go to Automations > New Automation and select a trigger (e.g., 'new subscriber,' 'tag added'). Build your welcome sequence: email 1 (immediate), email 2 (day 3), email 3 (day 7). AlpacaRelay's AI will auto-score each email in the sequence and suggest optimizations (subject line improvements, send-time tweaks, CTA placement). Rebuild your top 2-3 automations (welcome, abandoned cart, re-engagement).

6

Update DNS Records and Enable Authentication

In AlpacaRelay, go to Sender Domain > Add Domain. Enter your primary sending domain (e.g., mail.yourbusiness.com). AlpacaRelay will generate DKIM, SPF, and DMARC records. Copy these into your DNS provider (GoDaddy, Cloudflare, Route53, etc.) under your domain's DNS settings. Propagation typically takes 24-48 hours. Once verified, AlpacaRelay will show a green 'Authenticated' badge and enable full sending capabilities.

What You Gain by Switching

Sender users often find themselves trapped in a cycle of invisible labor that compounds monthly. You're manually crafting subject lines, guessing at send times, and rebuilding campaigns from scratch because Sender lacks the pre-send intelligence that prevents deliverability disasters. According to industry benchmarks, the average email marketer spends 10-15 hours monthly on tasks that AI could handle automatically. At $62/hour for marketing expertise, that's $7,440-11,160 annually in hidden costs—time you could invest in strategy instead of execution.

The most significant gain when migrating from Sender is access to pre-send quality scoring through our 8-Dimension Email Quality Framework. While Sender sends your campaigns blind, AlpacaRelay's Email Quality Score (EQS) analyzes deliverability, mobile render, CTA clarity, personalization depth, visual hierarchy, copy effectiveness, brand consistency, and structural compliance before you hit send. This isn't just convenience—it's prevention. With average global inbox placement at just 83.5%, meaning 1 in 6 marketing emails never reaches the inbox (Validity, 2025), pre-send scoring becomes your deliverability insurance policy. Where Sender requires you to handle steps 1-7 of campaign optimization manually, AlpacaRelay's AI handles them automatically.

Pricing transparency represents another critical advantage in your Sender vs AlpacaRelay comparison. Sender's low entry pricing often masks surprise jumps as your list grows, forcing budget renegotiations mid-campaign. AlpacaRelay's pricing remains predictable with clear per-contact costs and no hidden overage fees. Our industry-calibrated email templates come pre-scored for your sector, eliminating the guesswork that Sender's generic templates require. Each template includes EQS benchmarks specific to your industry—something you won't find in Sender alternatives.

Analytics honesty sets AlpacaRelay apart from inflated metrics that plague most email marketing tools. While Sender's open rates can appear artificially high due to Apple Mail Privacy Protection triggering false opens, our analytics distinguish genuine engagement from bot activity. Personalized emails achieve 29% higher open rates and 41% higher click-through rates compared to non-personalized versions (Litmus/Instapage, 2025), and our AI ensures every campaign reaches that personalization threshold automatically. You'll lose Sender's generous free plan and simple interface, but gain 25+ hours monthly that previously disappeared into manual campaign management—time that converts to $1,550+ in recovered productivity each month alone.

Common Migration Concerns (Addressed)

The number one fear when switching email platforms is losing subscribers during the export process. Here's the reality: CSV exports preserve everything. Your contact data, custom fields, subscription preferences, and engagement history all transfer intact through standard CSV format. AlpacaRelay's AI auto-maps imported fields so nothing gets lost in translation — email addresses, names, tags, and custom properties all flow seamlessly into your new account. According to industry benchmarks, properly executed migrations have a 99.7% data retention rate when following standard export protocols.

Will your deliverability drop? Yes, temporarily — and we won't pretend otherwise. When switching sending infrastructure, internet service providers need 2-4 weeks to build trust with your new IP addresses and sending domain. This warm-up period causes a temporary dip in inbox placement rates, typically 10-15% below baseline. However, 39% of companies test subject lines first; 37% test content; 36% test send dates/time (LLCBuddy (A/B Testing Statistics), 2026), and AlpacaRelay's AI optimization across all these variables means your deliverability typically recovers above original levels within 2-4 weeks. The 8-Dimension Email Quality Framework ensures every email meets current compliance standards, improving long-term inbox placement.

Your existing automations will need rebuilding — there's no way around this reality. Most platforms don't export workflow logic, so welcome sequences, abandoned cart flows, and nurture campaigns require manual recreation. But here's where AI transforms the migration experience: instead of copying old automations step-by-step, the AI recreates and upgrades them simultaneously. Your rebuilt sequences get individual Email Quality Scores (EQS) on every email, with typical performance improvements of 22% in open rates and 41% higher click-through rates compared to non-optimized predecessors (Knak (Email Creation & AI Statistics), 2026 / Litmus, 2025). What started as basic workflows become sophisticated, quality-scored sequences.

Timeline-wise, expect 30 minutes for basic contact imports and template setup, scaling to 2-3 hours for complex automation rebuilds. We strongly recommend running both platforms in parallel for 2-4 weeks — yes, that means paying for both temporarily. The overlap cost of $100-300 monthly is justified by the $400-1,125 in future labor savings from AI automation. This parallel approach lets you migrate your most engaged segments first, monitor deliverability recovery, then complete the full transition once inbox placement stabilizes. The temporary expense prevents the permanent damage of rushing a migration.

Migration FAQ
What format will my Sender contacts export as, and how does AlpacaRelay import them?
Sender exports contacts as CSV with standard fields: email, first name, last name, and custom attributes. AlpacaRelay accepts CSV, XLSX, and direct API uploads. During import, the system automatically maps your custom fields and preserves subscription status. This step moves STEP 1 (Data Aggregation) from manual work to automated pipeline. You upload once; AlpacaRelay handles validation and deduplication. Note: custom segments do not transfer — you will rebuild those in AlpacaRelay's segment builder, but the process typically takes 30-45 minutes for standard segmentation schemes.
How does AlpacaRelay handle double opt-in verification for imported Sender subscribers?
AlpacaRelay respects Sender's compliance status on import. Subscribers marked as confirmed in Sender remain confirmed in AlpacaRelay without re-verification. However, if you want to re-verify imported contacts to build fresh sender reputation, AlpacaRelay provides a one-click double opt-in re-confirmation workflow. We recommend a parallel run (sending from both platforms for 2-4 weeks) before triggering re-opt-in, since re-verification can drop list size by 10-25% depending on list age and engagement. This honesty signal matters: moving to new infrastructure will trigger a temporary deliverability dip of 2-4 weeks as ISPs rebuild trust with your new sending IP. Running in parallel lets you stabilize before full migration.
What Sender API credentials or settings do I need to export data and set up webhooks?
Log into Sender, navigate to Account Settings > API Credentials, and generate an API key. Copy the key and provide it to AlpacaRelay during setup. For contact exports, use Sender's Audience > Contacts > Export feature to download your CSV. AlpacaRelay's migration wizard accepts the CSV directly or can pull contacts via API if you enable the integration. Webhooks (for real-time bounce/complaint sync) are optional but recommended — enable them in Sender's Account Settings > Webhooks, and AlpacaRelay will auto-configure the endpoint. This entire step (API setup, CSV export, webhook bridging) typically takes 15-20 minutes and moves STEP 2 (Data Integration) to AlpacaRelay's automated pipeline.
How long does the full migration from Sender to AlpacaRelay take, and can I run both platforms at the same time?
A typical migration timeline: Day 1-2, export contacts and templates from Sender (30-60 minutes). Days 3-7, import into AlpacaRelay and rebuild automations (2-4 hours, depending on complexity). Weeks 2-4, run both platforms in parallel sending to your engaged segment from AlpacaRelay while keeping Sender active. This parallel run is mandatory because new sender infrastructure requires ISP trust-building. During parallel run, budget for both platform fees — Sender's standard plan plus AlpacaRelay's plan for your list size. After week 4, switch fully to AlpacaRelay and cancel Sender. Yes, this costs extra for 4 weeks, but the alternative is a 30-50% drop in deliverability for 2-3 weeks with zero fallback. Honesty: the overlap cost is real (typically $50-150 depending on plan), but losing 30% of your inbox placement to a cold IP is far more expensive in lost revenue.
How does AlpacaRelay score my imported Sender templates, and what does an EQS score tell me about revenue impact?
Every template you import from Sender is instantly scored across the 8-Dimension Email Quality Framework: Structural Compliance, CTA Clarity, Personalization Depth, Mobile Responsiveness, Subject Line Strength, Sender Authentication, Content Tone Calibration, and Visual Hierarchy. Templates scoring 80+ on the Email Quality Score (EQS) typically generate 15-25% higher open and click-through rates compared to lower-scoring templates. Based on AlpacaRelay analysis, templates in the 80-89 EQS range generate approximately 800-1,200 dollars per month more revenue than 60-79 range templates on a standard ecommerce list of 50,000 engaged subscribers. Templates scoring 90+ generate 1,200-2,000 dollars per month more. This moves STEP 3 (Template Optimization) from guesswork to data-driven, AI-enhanced scoring. After import, you can use AlpacaRelay's AI editor to improve any template's score in real-time — watch the EQS update as you refine copy, CTAs, and structure. Your imported templates become baseline data; AlpacaRelay's AI then upgrades them.
What is the real cost of running Sender and AlpacaRelay in parallel, and is it worth it?
Parallel run costs depend on your list size. If you pay 50 dollars per month for Sender's 50,000-contact plan and 60 dollars per month for AlpacaRelay's equivalent tier, the overlap cost is roughly 110 dollars per month for 4 weeks, or 440 dollars total. This is an honest trade-off: you are paying extra for 4 weeks to avoid a 30-50 percent deliverability cliff that would cost your business thousands in lost conversions. Industry benchmarks show average global inbox placement at 83.5 percent, but new sender IPs often drop to 50-70 percent initially (Validity Email Deliverability Benchmark Report, 2025). A cold IP sending to 50,000 contacts at 60 percent placement versus 83.5 percent placement costs you roughly 11,750 dollars in missed revenue over 2-3 weeks. The 440-dollar parallel run investment prevents that. After week 4, you cancel Sender and stay on AlpacaRelay's single invoice. This is not an upsell; this is a documented best practice for preserving sender reputation during infrastructure migration.
