Android gives you more room than iOS here, but the built-in messaging apps still stop well short of comfortable mass texting. Here is what works natively, and where a dedicated app earns its place.
What Google Messages can do on its own
Google Messages will send to multiple recipients, and it lets you choose how:
Settings ▸ Advanced ▸ Group messaging offers two options:
- Send an SMS reply to all recipients — individual messages. Each person gets a private text and replies come only to you.
- Send an MMS reply to all recipients — one shared group thread where everyone sees everyone.
For an announcement to customers you want the first. The reasoning is in group text versus individual texts, and it matters more than it sounds.
Samsung Messages exposes the same choice, usually as a “Group conversation” toggle on the compose screen rather than in settings.
What neither gives you: saved distribution lists that are not contact groups, reusable templates, per-contact personalisation, CSV import, automatic batching, or a record of what you sent to whom.
Why a helper app opens your messaging app
You may wonder why an Android app that helps you text a list still hands you off to Google Messages or Samsung Messages at the end.
Android does have a framework API for sending an SMS directly. Using it in practice requires the app to become your default SMS app — taking over every conversation on your phone, receiving all your incoming messages, replacing the app you already use. Google Play also restricts the underlying permission to apps whose core function requires it.
Our app deliberately does not go that way. Becoming your entire messaging system in exchange for one feature is a bad trade, and the send belongs in the app you chose and trust: that is where your conversations live, where your carrier settings are right, and where a failure will actually tell you it failed. So the app assembles everything — recipients, message, personalisation, batch — and opens your default messaging app pre-filled. You confirm, and the message lands in your real thread history like any other.
The longer version of that argument covers iOS too.
The practical flow
With our Android app:
- Build the list — an Android contact group, a distribution list you saved in the app, or a CSV import.
- Clean it — the Smart Cleaner finds duplicate contacts and flags numbers that are malformed and would fail silently. On a list built up over years this alone is worth the trip.
- Pick a template or write the message and save it for next time.
- Personalise if you want each message to carry the recipient’s own name.
- Let the wizard batch it — large lists are split into blocks sized to stay inside carrier rate limits, and the wizard walks you through them rather than firing everything at once.
- Confirm each batch in your messaging app.
- Check the history afterwards to see what went out and when.
For anything that repeats, the Agenda tab holds scheduled messages: you plan the send, get a notification when it is time, and confirm then. Past and upcoming sends live in the same place.
You can also compose to WhatsApp or Telegram for contacts you would rather reach there, which for some lists is both cheaper and more likely to be read.
Keeping a big send reliable
Batch it. Carriers rate-limit aggressively, and a single 400-recipient send is far more likely to be throttled or silently dropped than eight sends of 50. The app’s batch size is configurable for exactly this reason — see carrier limits.
Watch the encoding. One emoji or accented character drops the per-message limit from 160 characters to 70, turning one message into three. On 400 recipients that is a real bill.
Test on yourself. Two of your own numbers, before the real send.
Check MMS costs before attaching a picture to a large list. MMS is frequently billed separately from SMS.
Step by step
- Set your messaging app’s group setting to individual SMS, not group MMS, for announcements.
- Build and clean the recipient list, removing duplicates and invalid numbers before you send anything.
- Write the message once as a template, keeping it inside one SMS part where possible.
- Add name personalisation so each message reads as a personal one.
- Split the send into batches rather than one large blast.
- Send a test to yourself, then confirm each batch in your default messaging app.
Questions people ask
Can an Android app send SMS without opening my messaging app?
Only if it becomes your default SMS app, taking over all your messaging. Ours does not: it pre-fills your existing messaging app so the send happens where your conversations already live.
How do I text a contact group on Android?
Google Messages can address a contact group, but you still choose between individual messages and a group thread, and you get no templates or personalisation. An app that reads your groups and adds those features is the practical route.
How many texts can I send at once on Android?
There is no fixed number — carriers throttle based on their own thresholds, often somewhere around 20–100 messages in a short window. Batching with pauses is what keeps a large send reliable.
Will my recipients see each other?
Only in a group MMS thread. Individual SMS hides all other recipients.
Does the app store my contacts anywhere?
No. Contacts stay on your phone; nothing is uploaded to a server. That is a direct consequence of sending through your own phone rather than through a gateway.
