Text to email: how businesses get text replies where the team works

To send a text to email from your phone, type the email address into the "To" field of your messaging app instead of a phone number, write your message and hit send. Your phone delivers it as an MMS (or as an iMessage, if the address belongs to an Apple ID), and the reply comes back to your phone as a text.

That works for one person sending one note. It does not work for a business that needs every customer text seen, answered and recorded, even when the person who owns the phone is on vacation. This post covers the phone method first, then why it falls short, then how teams route inbound texts into a shared inbox, their own systems or a helpdesk using the Ready inbox and REST API.

How to send a text to an email address from your phone

The steps are nearly identical on both platforms.

On iPhone

1. Open Messages and start a new message.
2. Type the full email address in the "To" field.
3. Write the message and send.

If the address is tied to an Apple ID, the message goes as an iMessage and shows up in that person's Messages app, not their inbox. If it isn't, the iPhone sends it as MMS through your carrier, and it arrives as an email from an address based on your phone number.

On Android

1. Open your messaging app (usually Google Messages) and start a new conversation.
2. Enter the email address as the recipient.
3. Send. The app converts it to MMS automatically.

The email arrives from a carrier-generated address. If the recipient replies to that email, the reply usually lands back on your phone as a text. Delivery depends on your carrier, your data connection and whether MMS is enabled on your plan.

The reverse direction: email to text

People searching "sms to email" often mean the opposite: sending an email that arrives as a text. For years that ran through carrier email-to-SMS gateways (an address like your-number@carrier-domain). Carriers have been retiring or restricting these gateways, and messages through them are often filtered as spam. For anything a business depends on, treat them as unreliable.

Why text to email falls short for a business

The phone method treats texting as something one person does from one device. Business texting is a team doing it for a list of customers. Here's where it breaks.

• Replies land on one personal phone. A customer who replies to a quote or appointment text reaches whoever sent it. If that person is off, out sick or gone from the company, the conversation goes with them.
• No shared view. Nobody else can see the thread, pick it up or tell whether it was answered.
• No opt-out handling. If a customer texts STOP to a personal phone, nothing stops a coworker from texting them next week. Your own sender's opt-outs become a manual spreadsheet problem.
• No audit trail. There's no record of who sent what, to how many people, and when.
• Carrier filtering. Business texts sent from personal numbers aren't on a registered A2P 10DLC campaign. Carriers filter unregistered business traffic, so messages may quietly never arrive. (Our 10DLC explainer covers why.)
• It doesn't scale. MMS-to-email works for a handful of messages. It is not a way to answer 300 customer replies a week.

None of these are edge cases. They're the normal state of a team that texts from personal phones.

What "text replies where the team works" actually means

The goal behind most text-to-email searches is simple: when a customer texts us, the right person sees it quickly, and nothing gets dropped. Email is just the place many teams already look. There are three ways to get there, and they suit different teams.

Option 1: a shared inbox for inbound texts

In Ready, every inbound text lands in an Inbox tied to the business number, not to anyone's phone. Two-way threads sit in one place, so anyone on the team can read a conversation and reply from the same number the customer already knows.

A few details matter for routing:

• Opt-outs are automatic. When a customer replies STOP or UNSUBSCRIBE, Ready honors it, and the opt-out applies across campaigns so that contact can't be texted again by mistake.
• Quiet hours are enforced. Campaign and automation sends outside permitted local hours for the recipient's area are held and go out later; a one-to-one or API text is held only if the window opens within about 6 hours, otherwise it is refused and you send it again.
• Registration is part of setup. Brand and campaign registration happen in-app. Most approvals take 2 to 7 days.
• GoHighLevel users keep their workflow. If your team lives in GoHighLevel, Ready installs natively via OAuth and syncs inbound and outbound messages two ways, mapped per GHL location, so replies show up in the GHL conversations view. Our GHL setup guide walks through it.

For the predictable replies (hours, directions, "got it, thanks"), templates save typing, and our auto reply text message examples give you wording to start from. Ready's AI message writer helps draft and spam-check messages, but a person sends the reply. Ready no longer lets accounts create AI reply agents that answer customer texts on their own.

Option 2: route inbound texts with the REST API

If your team works in a helpdesk, a Slack channel or your own product, the cleaner pattern is to pull texts out of Ready and push them wherever your people already work. That includes email, if email really is your team's home base. You build the last hop, and Ready handles the number, registration, opt-outs and delivery.

Reading messages is one authenticated call:

curl https://api.tryready.com/v1/messages \
  -H "X-API-Key: YOUR_API_KEY"

GET /v1/messages returns your messages and pages with before_id, so a scheduled job can fetch new texts and forward them to an email address, a ticket queue or a channel. For push delivery instead of polling, Ready has webhooks built in. The inbound_reply event is in the webhooks docs. Check the X-Signature header on every event before you forward it, so a forged POST to your endpoint goes nowhere; here is how.

Replying from your system is the same API:

curl -X POST https://api.tryready.com/v1/messages \
  -H "X-API-Key: YOUR_API_KEY" \
  -H "Idempotency-Key: 3f2b8c1e-9a4d-4e7b-b6a1-2c5d8e0f1a93" \
  -H "Content-Type: application/json" \
  -d '{"to": "+12125550199", "body": "Thanks, we have you down for Thursday at 10 AM.", "consent_attested": true}'

The Idempotency-Key header means a retried request never sends twice. consent_attested is your promise that the recipient agreed to texts. Ready records that attestation per send as an audit trail. Opted-out numbers are refused before sending and aren't charged. You can also check an individual opt-out with GET /v1/opt-outs/:phone before your system replies.

For platforms texting on behalf of their own customers, each customer gets a sub-account with its own numbers and registration. Our A2P SMS API post covers that architecture. The quickstart gets a first send working.

What routing inbound texts costs

Replies you receive are billed like sent texts: $0.0075/segment plus a $0.0045 carrier fee per segment, on one Standard rate. Billing is prepaid credits, with carrier fees itemized separately.

Worked example (assumptions stated): a service business gets 400 inbound customer texts a month and sends 400 replies. All messages are under 160 plain characters with no emoji, so each is 1 segment.

• Segments: 400 inbound + 400 outbound = 800
• Rate: 800 × $0.0075 = $6.00
• Carrier fee: 800 × $0.0045, itemized separately
• Registration: $25/mo for registration + $2 per number. With one number that's $27/mo, and the first month ($25) is charged at submit with no setup fee.

Two things change that math. First, an emoji drops a segment to 70 characters, so a 140-character reply with one smiley becomes 3 segments, not 1. Second, TCPA/DNC scrubbing and landline validation each add $0.003 per segment if you switch them on for the account. Both are off by default. Our 10DLC cost breakdown itemizes the registration side in full.

To be plain about it: per message, raw CPaaS APIs such as Twilio (~$0.0083/segment) and GoHighLevel's LC Phone (~$0.0083/msg) cost less. What Ready adds is the registration done in-app, opt-outs, quiet hours, the inbox and the API in one place. If you have engineers who want to build those pieces themselves, a raw API is a reasonable choice.

Which approach fits your team

• You text a few people a month, personally. The phone's text-to-email method is fine. You don't need a platform.
• A small team answers customers by text. Use a shared inbox, in the Ready app or GoHighLevel. Everyone sees every thread.
• Your team works in a helpdesk, Slack or email. Use the API to forward inbound texts there and reply from the same system.
• You're a platform texting for your customers. Use sub-accounts plus the API, so each customer's numbers, registration and conversations stay separate.

The practical takeaway

Texting an email address from your phone is a neat trick, and it answers the literal question. For a business, the real need is that customer texts land somewhere shared, get answered from a registered number, respect STOP and leave a record. That means a shared inbox, or an API that routes texts into the tools your team already uses.

If you want to try it, the first 20 one-to-one texts on Ready are free, so use them to test the inbox before you register. To send, you add a card and get a number, which is $2 a month with the first month charged when you get it. You can sign up here or browse the features first.

FAQ

Can I send a text message to an email address? Yes. Type the email address into the recipient field of your phone's messaging app and send. It goes as MMS, or as an iMessage if the address is an Apple ID, and replies come back to your phone as texts.

Does sending a text to email cost anything? On a personal phone it uses your plan's MMS allowance. In Ready, sent and received texts are both billed at $0.0075/segment plus a $0.0045 carrier fee.

Can business texts be forwarded to email automatically? Ready puts inbound texts in a shared Inbox, synced to GoHighLevel for connected accounts. To get them into email, a helpdesk or Slack, pull them with GET /v1/messages or use webhooks, then forward them from your own code.

What happens if a customer texts STOP? Ready honors STOP and UNSUBSCRIBE automatically, and the opt-out applies across campaigns. Later sends to that number are refused before they go out and aren't charged.

Do I need 10DLC registration to receive and answer customer texts? For ongoing business texting, yes. An account can send up to 500 texts a month before registering, and after that it has to register. Most approvals take 2 to 7 days.
