Create beautiful RSVP emails with video in 30 minutes, not 3 hours.
AlpacaRelay combines event-specific templates, one-click video embedding, and MessageBird SMS integration to eliminate fragmented tools and manual tracking.
Join 5,000+ event marketers sending 10M+ RSVP emails annually. Average RSVP response rate: 40% (vs 24% with text-only invitations).
Event invitations are taking over your life.
You're spending 3-5 hours per campaign juggling design tools, email builders, video hosting, and RSVP forms. Your responses are scattered across email, SMS, and spreadsheets. And your RSVP rates are stuck at 20-25% because generic templates don't inspire attendance.
3-5 hours per campaign
Creating professional invitation emails requires jumping between design tools, email builders, video hosting platforms, and manual integration. By the time you're done, you're exhausted.
Fragmented RSVP tracking
Responses come via email replies, form submissions, text messages, and manual entries. No unified view. Error-prone. Nobody knows actual attendance until 24 hours before event.
Low response rates (20-25%)
Generic email templates don't create excitement. Recipients delete without responding. You miss registration targets and struggle to plan venue capacity and catering.
Video embedding is a nightmare
Video doesn't render properly across all email clients. You spend hours troubleshooting fallbacks. Half your audience sees a broken experience.
No SMS follow-up capability
Email-only approach leaves 10-15% of recipients unreached. No way to send SMS reminders to non-responders or day-before attendance confirmations.
No visibility into effectiveness
You don't know if people watched embedded videos or which content drove RSVPs. Impossible to optimize campaigns or justify multimedia investment.
We understand. We spent years managing events the same way. We've been there at 4 PM realizing invitations aren't going out until tomorrow, wishing we had a faster way. We built AlpacaRelay to solve this once and for all.

Six ways AlpacaRelay transforms your event invitations
Select event template → Upload video → Customize details → Send. Pre-built RSVP components and AI-suggested copy eliminate 90% of manual work. What took 3+ hours now takes less than one.
✓ Average user sends first campaign in 18 minutes without external support. Sarah (Event Manager) reduced invitation creation from 3.5 hours to 45 minutes per campaign.
Video-rich invitations with compelling visual preview increase perceived event value. MessageBird SMS reaches non-email responders. Combined effect: 40% RSVP rate vs 24% baseline with text-only invitations.
✓ Marcus (Development Director) increased fundraiser RSVP rate from 22% to 38% (1,500-person list = 200 additional confirmed attendees per campaign). Real estate agent David lifts response from 24% to 38% with property tour video.
All responses—email replies, SMS confirmations, form submissions—appear in single dashboard with real-time status, timestamps, and guest list export. No spreadsheet reconciliation. 99% accuracy vs 87% manual tracking.
✓ Eliminates 3-4 hours/week of manual RSVP management for teams running 5+ concurrent events. One-click export to catering, venue, logistics teams. Headcount finalized 1 week before event instead of 24 hours before.
MessageBird SMS integration sends automatic follow-ups to email non-responders within 48 hours and day-before event reminders to all RSVPs. Captures additional 10-15% responses. Reduces no-show rate by 8-12%.
✓ SMS follow-up on 5,000-person event list reaches 500-750 non-responders; 10-15% conversion yields 50-110 additional RSVPs. David's open house SMS reminders convert 60% RSVP attendance to 72% actual attendance.
Native cross-client testing across 20+ email clients (Gmail, Outlook, Apple Mail, mobile). Automatic mobile optimization. Video fallback design for unsupporting clients ensures 99.2% successful rendering. Zero 'broken email' surprises.
✓ 8,000-email conference campaign rendered perfectly in 99.1% of inboxes (99.2% average across all campaigns). Eliminates 45-60 minutes of rendering troubleshooting per campaign. Prevents emails appearing broken on recipient devices.
Built-in analytics show video play rate, RSVP-to-attendance conversion, email open timing, and engagement by video type. Measure what actually drives attendance. Optimize future campaigns with data-backed insights.
✓ Tech conference case study: 41% of opened emails played embedded video. Email open rate 34% vs 28% industry average. Data visibility enables 15-20% improvement in future campaigns through optimization.

From event marketers solving the problem every day
Hear how AlpacaRelay helps marketers, designers, and founders create better emails together.
“We used to spend 3-4 hours creating one invitation email, managing video uploads, and manually tracking RSVPs in spreadsheets. With AlpacaRelay, I select a template, upload a video, customize event details, and send in 45 minutes. All RSVP responses appear in one dashboard instantly. Changed how we run events.”
Sarah Chen
Event Marketing Manager, Acme B2B Services
“Adding a video message from our executive director to fundraiser invitations and following up with SMS to non-responders lifted our RSVP rate from 22% to 38%. That's 200 additional attendees on a 1,500-person list. The ROI is insane—the subscription pays for itself in one campaign.”
Marcus Williams
Development Director, Community Foundation
“Open house invitations are everything to my business. I embed a 2-minute property tour video and send SMS reminders day-of to confirmed RSVPs. Attendance went from 60% of RSVPs to 72%. SMS follow-up captures an extra 10-15% of interested buyers I'd otherwise miss. Game changer for conversions.”

Zero broken email states; automatic fallback design for unsupporting clients
No. AlpacaRelay works alongside your existing email platform. Think of it as specialized 'event invitation studio'—your CRM owns your contact data, and we handle event template creation and RSVP tracking. Your RSVP data syncs back to Mailchimp/HubSpot as contact custom fields. 92% of users keep their existing platform and use AlpacaRelay specifically for RSVP campaigns (2-3/month) while using their CRM for newsletters and nurture sequences.
You're right that video rendering is technically complex—but we've solved it. We use AMP for Email (where supported) + HTML5 fallback + high-quality thumbnail image + text fallback. Recipients always see something beautiful, never a broken state. Our testing shows 99.2% successful rendering across 20+ major email clients. For the 0.8% that don't support video, recipients see a professional thumbnail image with play button and click-through to video landing page. Zero reputation damage incidents across 10M+ emails sent.
MessageBird is a 15-year-old, publicly-traded SMS platform handling 90 billion messages/year for enterprises. SMS failure rate is <0.1%. Compliance is core to their business: CAN-SPAM, GDPR, TCPA all built in. Our SMS is always opt-in (only RSVP confirmations + pre-event reminders), not marketing spam. We provide transparent SLA documentation (99.9% uptime). We've sent 10M+ RSVP SMS across 2,000+ campaigns with zero compliance incidents. MessageBird carries compliance insurance. Enterprise plans include additional compliance consulting.
ROI isn't about email cost—it's about your time and campaign effectiveness. If you spend 3 hours per event invitation and run 3/month, that's 36 hours/year at ~$50/hour loaded cost = $1,800/year in labor. AlpacaRelay is $30-50/month = $360-600/year. Payback through labor savings: 2-3 campaigns. Additional ROI: 25% RSVP improvement on average 1,000-person event = 60 additional RSVPs per campaign = 180 additional confirmed attendees/year. At $50 value per attendee (venue capacity, catering, etc.), that's $9,000+ annual business impact from RSVP improvement alone. Subscription cost: $480-600/year. That's 15:1 ROI.
AlpacaRelay is actually faster to learn than your current email builder. Most users send their first RSVP campaign within 30 minutes of signup, no training required. We handle the complexity behind the scenes; you just click 'Create Event Email' and answer simple questions (event type, date, video upload). Onboarding is a 5-minute video walkthrough + pre-built templates you copy-paste. For enterprise customers, we offer white-glove setup calls. Video tutorial library covers every feature. Dedicated Slack channel for questions. 94% of new users rate learning curve as 'minimal' or 'easy'. Average time to first campaign: 18 minutes.
For small internal meetings (under 50 people), you might not. But most internal events—quarterly town halls, off-sites, training sessions, all-hands meetings—benefit from fast professional invitations and accurate headcount tracking. Video is optional (CEO prerecorded message, office tour, training preview all boost engagement). SMS is optional too. Skip SMS and save $20/month. But headcount accuracy is critical—nothing worse than catering for 50 when 120 show up. AlpacaRelay eliminates manual spreadsheet tracking. Basic plan ($20/month) still saves 1.5+ hours per campaign and improves RSVP accuracy from 87% to 97%.
Your contact data never touches AlpacaRelay servers. Your CRM (HubSpot, Salesforce, Mailchimp, etc.) owns contact data. When you send a campaign, you authorize via API token; we don't access or store contact emails. AlpacaRelay only stores campaign templates, RSVP responses, and metadata. SOC2 Type II certified. GDPR, CCPA, TCPA compliant (HIPAA available on enterprise plans). Encryption at rest (AES-256) and in transit (TLS 1.2+). You control data retention; can request full deletion anytime. We never sell or share data. Only your authorized team members can access campaign data based on role/permissions you set. Zero data breaches in 5 years.
