Frequently Asked Questions
What is A2P SMS and how is it different from regular SMS?
A2P stands for Application-to-Person. It's SMS sent from a software system to a person — not person-to-person texting. Think: order confirmations, appointment reminders, OTP codes, marketing campaigns. A2P requires carrier registration (Signal House handles 48-hour A2P approval) and a dedicated sender ID or number. Regular SMS from your phone is P2P. A2P is what businesses use at scale — with proper deliverability, tracking and compliance built in.
Why SMS and not just email or WhatsApp?
SMS open rates sit at 98% — email averages 20%. SMS doesn't require an app, an internet connection, or an opt-in to a specific platform. It lands on the phone directly. For time-sensitive messages (appointment reminders, delivery alerts, 2FA codes, event updates), SMS is the most reliable channel available. WhatsApp and ManyChat handle conversational engagement. Signal House handles guaranteed delivery.
What is the difference between ManyChat and Signal House?
ManyChat handles conversational channels — Instagram DMs, WhatsApp flows, Facebook Messenger sequences. Signal House handles A2P SMS and voice API — transactional messages, broadcast campaigns, and programmatic voice calls. ManyChat is best for social engagement and lead capture. Signal House is best for reaching people via text or voice when no app is required. In a complete messaging stack, both have a role — and n8n connects them.
What is ElevenLabs and how does it fit into business messaging?
ElevenLabs is an AI voice generation platform. In a business messaging context, it sits alongside Signal House's voice API — you write the script, ElevenLabs generates a realistic AI voice, and Signal House delivers it as a voice call or IVR message. Use cases: automated customer notifications via voice, AI-generated voicemail drops, multilingual voice campaigns, and accessible content for users who prefer audio over text.
How does n8n connect the messaging stack?
n8n is the automation backbone. A customer books an appointment → n8n triggers a Signal House SMS confirmation. They don't confirm → n8n sends a ManyChat WhatsApp follow-up. Still no response → n8n triggers an ElevenLabs voice reminder via Signal House. All automated. All tracked. No manual follow-up. This is what a modern business messaging workflow looks like when the tools are connected.
Is SMS marketing legal in Malta and the EU?
Yes — with opt-in. GDPR requires explicit consent before sending marketing SMS to EU recipients. Transactional SMS (confirmations, alerts, OTPs) generally doesn't require marketing opt-in but must be clearly transactional. Signal House's A2P infrastructure handles sender registration and deliverability — but compliance (opt-in collection, unsubscribe handling) is your responsibility. Always maintain a clean, consented list.
How much cheaper is Signal House vs Twilio?
Signal House is up to 90% more cost-efficient than Twilio for A2P SMS. Twilio is the dominant player but prices at enterprise scale. Signal House delivers comparable deliverability and reliability at a fraction of the cost — with white-glove support included and 48-hour A2P approval. For growing businesses sending thousands of messages per month, the cost difference is significant.
