FAQ

Can I send more than one message per contact in a session? Yes. The 15-minute spacing applies to contacts who have never replied. Within active conversations, send multiple messages freely.

Does a follow-up to someone who hasn’t replied count as a new contact? Yes. Any message to a contact who has never replied is treated as a new conversation initiation and uses a 15-minute slot, regardless of how many times you have messaged them before.

Is the 1,000 contacts per day a hard limit? It is a recommendation from Apple rather than a hard block, but exceeding it increases the risk of your number being flagged. For most accounts the 15-minute initiation rule is the binding constraint well before this number is reached.

Do the limits reset each month? There is no monthly quota. Limits are evaluated on a rolling 24-hour basis and per message interval.

Can I send outside 9:00 AM – 9:00 PM? Outbound initiations are held to the sending window to protect deliverability and avoid Report Junk. Replies to inbound messages are not restricted by the window.

What happens if my message gets blocked? Atlas Blue automatically re-queues it. No action needed.

What happens if I submit more messages than my daily capacity? Nothing is rejected. Messages queue and send as slots open inside the sending window. Messages that become eligible after 9:00 PM are held until 9:00 AM the next day.

Can I include a link in a follow-up if they haven’t replied? No. Content restrictions stay until the contact replies.

Why are these limits necessary? Atlas Blue runs on a physical iPhone connected to Apple’s iMessage network. If even two or three contacts tap Report Junk, Apple may stop delivering messages from your number entirely. These guardrails keep your number in good standing.

What about SMS fallback? If a contact is not reachable on iMessage, Atlas can fall back to SMS or RCS depending on your plan. SMS fallback is intended for two-way conversations — carriers filter SMS content that looks like marketing and may not deliver it. RCS provides delivery and read receipts and is the recommended fallback for outbound campaigns.

How long for a new phone number to go live? Up to 24 hours after purchase. You’ll receive an email when ready.

Can I test my agent before going live? Yes. Use the Test Messaging button on the campaign detail page.
