Blue bubble texting for business costs $99 a month per line plus 6 cents a segment, and each line can start up to 50 new conversations a day. It beats green SMS for one-to-one conversations where a named, photo-backed thread helps, or where you can't wait for 10DLC approval. Registered SMS is still the right channel for campaigns, drip campaigns and anything high-volume or price-sensitive.
This post covers what you get for the money, the per-conversation cost against registered SMS, how to work out how many lines you need, and what happens when the person you're texting has an Android phone. All the numbers are Ready's, because we make the product and those are the prices we can state accurately.
What blue bubble texting for business actually gets you
A blue line sends your texts as iMessage. On an iPhone the message shows up blue, with your business name and photo at the top of the thread, the same way a text from a friend does. Green SMS from a 10-digit number shows only the number, unless the person has saved you as a contact.
Teams usually want it for three reasons.
It reads like a person, not a system
A blue thread with a name and face looks like a conversation. A green thread from an unknown number looks like a notification, and plenty of people have learned to ignore those. We don't publish a reply-rate lift for blue lines, because it depends heavily on your audience and your message. This is the reason teams turn the feature on, and you should test it on your own leads before you budget around it.
No 10DLC wait
Registered SMS has to go through A2P 10DLC brand and campaign registration. On Ready that costs $25 at submit, which is the first month, and then $25 a month for registration and $2 per number. Most approvals take 2 to 7 days. Our 10DLC timeline breakdown covers each step.
A blue line needs no 10DLC registration. You can start texting as soon as the line is set up. If you have a sales team ready to work leads this week, that matters.
Replies, reactions and groups in one inbox
Replies, tapbacks, typing indicators and group chats land in the same inbox thread as your SMS conversations. Your team doesn't have to work a second tool.
What it is not
It is not Apple Messages for Business. That is Apple's service where the customer has to start the chat, usually from a button on your website or in Maps. A blue line can text first. That makes it useful for following up on a form fill, but it also means the usual consent rules apply. Text people who asked to hear from you or who have already been in touch, and keep cold outreach on the phone and in the mail. Compliance is the sender's responsibility whichever color the bubble is.
What it costs: blue line vs registered SMS
These are the line items side by side.
| Blue line (iMessage) | Registered SMS on Ready (Standard) | |
|---|---|---|
| Fixed monthly | $99 per line | $25 for registration + $2 per number |
| Per segment sent | $0.06 | $0.0075/segment plus a $0.0045 carrier fee |
| Per segment received | $0.06 | $0.0075/segment plus a $0.0045 carrier fee |
| Reactions | Free | n/a |
| Registration wait | None | Most approvals take 2 to 7 days |
| New conversations per day | Up to 50 per line | Set by carrier caps (T-Mobile starts at roughly 2,000 messages/day for the lowest trust score) |
| Campaigns and drip campaigns | No, these send from regular numbers | Yes |
| Photos | Only after the person replies | Yes, as MMS |
The SMS figures are all-in rates, which exclude the compliance surcharge. Scrubbing and landline validation are $0.003 extra per segment each when you switch them on for an account, and both are off by default. Our post on the carrier fee explains why that fee is listed separately on the bill.
Worked example: one sales line, 30 new leads a day
Assumptions, stated so you can swap in your own:
- 30 new conversations a day, 22 working days, so 660 new conversations a month
- Each conversation runs 4 segments out and 4 segments back, so 8 billed segments
- Every contact is on an iPhone (we relax this below)
Blue line:
- 660 × 8 = 5,280 segments
- 5,280 × $0.06 = $316.80 in segments
- Plus $99 a month for the line
Registered SMS (Standard), one number:
- 5,280 × $0.0075 = $39.60
- Plus 5,280 × $0.0045 in carrier fees
- Plus $27 a month for registration ($25 for registration + $2 number)
The blue line costs a lot more here. Per conversation, its 8 segments cost 8 × $0.06 = $0.48 against 8 × $0.0075 = $0.06 on SMS before the carrier fee, plus the $99 line spread over the month.
This changes how you frame the decision. You aren't asking whether iMessage is better. You're asking whether a named blue thread is worth that difference per conversation, plus $99 a month, for the leads you work. If each lead is worth a few hundred dollars and a slightly better reply rate wins you one extra deal a month, the line pays for itself. If you're texting appointment reminders that nobody replies to, it doesn't.
With Android in the mix
Not everyone uses an iPhone. Texts to Android phones go as regular SMS from the account's green number. If the account has no green number, a blue line comes with one, and then the account's texts bill at 6 cents a segment once it registers or when it sends through GoHighLevel.
Rerun the example assuming, for illustration only, that 60% of your contacts are on iPhone. Check your own split before you rely on it.
- iPhone: 3,168 segments × $0.06 = $190.08, plus the $99 line
- Android: 2,112 segments × $0.0075 = $15.84, plus 2,112 × $0.0045 in carrier fees
- Total: the two lines above added together, plus carrier fees on the Android share
That assumes the account already had its green number. If the blue line came with it, the Android share bills at 6 cents a segment once the account registers or sends through GoHighLevel.
The more Android users you have, the more of your traffic goes at SMS prices anyway, and the less the $99 line buys you.
The 50-a-day limit and how to plan line count
The limit catches most people out, so it's worth planning around before you buy.
The rules
- Unlimited texting with people you already talk to. Ongoing threads don't count against anything.
- Up to 50 new conversations a day per line. This is the constraint you size against.
- Up to 2 texts to someone until they reply. You can't send a five-message follow-up to a lead who has gone quiet.
- Photos only after they reply. Your opener is text-only.
How to size it
Size for your peak day, not your average. Count the new conversations you need to start on the busiest day of a normal week:
- Count peak new contacts per day. For example: 120 inbound leads on a Monday after weekend ads.
- Divide by 50 and round up. 120 ÷ 50 = 2.4, so 3 lines.
- Price the fixed cost. 3 × $99 = $297 a month before any segments.
- Decide what happens on overflow. You can add lines by hand, or turn on "Add lines automatically". That setting adds a line when the day's new conversations are used up, so a spike doesn't stall follow-up. It also raises your monthly cost, so watch it.
If your peak is 400 new contacts a day, you're looking at 8 lines, or 8 × $99 = $792 a month in line fees alone. At that point, ask whether blue is worth it for every lead or only for your highest-value ones. A common split is to send the first touch on registered SMS and move engaged replies onto a blue line. Another is to keep blue for one segment, such as high-ticket inquiries.
Write openers that earn a reply
The texts-until-reply limit changes how you write. The first message has to give the person a reason to answer:
- Use their name and mention what they asked about.
- Ask one easy question ("Is Thursday or Friday better for a quick call?").
- Leave out links and photos. Photos aren't allowed yet, and links in a first touch read like spam on any channel.
Once they reply, the thread is open, and photos, follow-ups and longer messages are all fine.
When green SMS is still the better channel
We'll say this plainly: for a lot of sending, registered SMS is the right tool and a blue line is the wrong one.
- Campaigns and drip campaigns. These send from regular numbers, not the blue line. If your program is a weekly promo to 20,000 opted-in customers, blue isn't an option for it.
- Transactional notifications. Order updates, reminders and verification codes rarely get replies. Paying 6 cents a segment for a name and photo doesn't change much.
- High new-contact volume. At 50 new conversations per line per day, starting thousands of conversations means a lot of lines. Registered SMS throughput is set by carrier caps instead. For a fresh standard campaign that's roughly 1 to 4 segments per second, and T-Mobile's daily brand cap starts at roughly 2,000 messages for the lowest trust score and goes up from there.
- Android-heavy audiences. Those contacts get green SMS regardless.
- Tight unit economics. If you're reselling texting to clients at a margin, the 6-cent blue segment leaves less room to mark up. Our SMS pricing buyer's guide walks through that kind of math.
The 10DLC wait is also shorter in practice than it sounds. An account can send up to 500 texts a month at its normal per-text rate before it registers. An account that bought its number before registering sends on Ready's shared registration while its own registration is in review. If the wait is the only reason you're looking at blue, that may be enough to cover the gap. Our 10DLC explainer covers registration from the start.
The setup most teams end up with
Most accounts that use a blue line run both channels:
- Registered SMS for campaigns, drip campaigns, reminders and anything that goes out to many people at once
- One or more blue lines for one-to-one sales and support conversations where the person is likely to reply
- The same inbox for both, so a rep sees one thread per contact whatever the bubble color
For platforms building this into their own product, blue lines have their own guide and API reference: blue line guide and blue line API. Regular SMS sending is covered in the messages API docs.
Frequently asked questions
How much does iMessage for business cost?
On Ready, a blue line costs $99 a month plus 6 cents per segment for each text sent. Replies to the blue line are also 6 cents a segment, and reactions are free. Texts to Android phones go as regular SMS from your green number. If the blue line came with that number, your account's texts bill at 6 cents a segment once you register or when you send through GoHighLevel; otherwise they're at the regular rate.
Do I need 10DLC registration to send blue bubble texts?
No, a blue line needs no 10DLC registration, so you can start texting as soon as the line is set up. Your regular green number, which handles Android contacts and all campaigns, is ordinary SMS, and the usual registration rules apply to it as your volume grows.
How many new people can one iMessage business line text per day?
Each blue line can start up to 50 new conversations a day. Texting people you're already talking to is unlimited. If you need more new conversations a day, add another line, either by hand or with "Add lines automatically".
What happens when I text an Android user from a blue line?
The text goes as regular SMS from your account's green number. If your account doesn't have a green number, the blue line comes with one, and then your account's texts bill at 6 cents a segment once you register or when you send through GoHighLevel; otherwise they're at the regular text price. The person sees a normal green text, without your name and photo.
Can I send marketing campaigns over iMessage?
No, campaigns and drip campaigns on Ready send from regular numbers, not the blue line. Blue lines are built for one-to-one conversations, with a limit of 2 texts to a new contact until they reply and photos only after a reply. Use registered SMS for anything that goes to a list.
The practical takeaway
A blue line is a premium channel for conversations, not a cheaper or faster way to send campaigns. It costs more per segment than registered SMS, plus $99 a line. You size it by how many new conversations you start on your busiest day. Android contacts get green texts, at the regular price if you already had a number, or 6 cents a segment if the blue line came with your number. It's worth paying for when a named, photo-backed thread helps you win replies on leads that are worth real money, or when you have to start texting today without waiting for registration.
To test it, run one line for a month on a single lead source. Compare reply rates and cost per conversation against the same leads on registered SMS, and decide from your own numbers. Current SMS pricing is on our pricing page, and you can create an account here whenever you want to set up a line.
