This guide explains how to send text messages (SMS) in PushPress Grow the right way — so your messages go through, your costs stay low, and your account stays in good standing.


What Is SMS in Grow?

SMS lets you text:

  • Leads

  • Members

  • Former members

You can send:

  • 1-to-1 texts

  • Group texts (using drip mode)

Each text message has a cost, and there are daily sending limits to protect your phone number.


Daily SMS Sending Limits (Ramp-Up Policy)

To protect your phone number and keep carriers happy, Grow uses a ramp-up system.

You cannot send unlimited texts right away.

Campaign Daily Limit

  • Maximum: 500 SMS per day for campaigns

  • Going over this limit can pause SMS sending for the day


How the Ramp-Up Works

When you first start sending SMS, Grow increases your limit slowly.

Stage

Max SMS per 24 hours

Stage 1

100

Stage 2

250

Stage 3

500 (daily cap)

Stage 4+

Stay at 500

Important:
You move to the next stage only after you hit the current limit and wait 24 hours.


Example

  • Day 1: You send 100 texts → you must wait 24 hours

  • Day 2: You can send 250 texts

  • Day 3: You can send 500 texts

This protects your number and builds trust with phone carriers.


Why This Matters

Sending too many texts too fast can:

  • Get your number flagged

  • Cause messages to fail

  • Lead to temporary SMS blocks

The ramp-up keeps your SMS working long-term.


Use Drip Mode for Group Texts (Very Important)

When texting groups, never send all messages at once.

Always use Drip Mode

Drip mode:

  • Sends texts in small batches

  • Spaces them out over time

  • Keeps you compliant with A2P rules

Recommended Drip Settings

  • 15–20 messages per hour

  • Spread messages across hours or days

  • Avoid late nights and early mornings


Consent & Compliance Rules (Must Follow)

You must follow texting rules to avoid suspension.

You MUST:

  • Have clear permission to text someone

  • Identify yourself in the message

  • Include opt-out language

    • Example: “Reply STOP to unsubscribe”

You MUST NOT:

  • Text people who didn’t opt in

  • Send mass marketing texts without consent

  • Harass, threaten, or mislead

  • Send illegal content (including THC/CBD - even if legal in your State of operation!)

  • Market to minors under 14


Common Reasons SMS Gets Blocked

  • High opt-out rate

  • Too many failed messages

  • Sending too many texts too fast

  • Poor message quality

Healthy Metrics

  • Opt-out rate: 0–0.3%

  • Error rate: 0–6%


SMS Costs (Know Before You Send)

Each text message has a cost.

How SMS Pricing Works

  • Cost per SMS segment: ~$0.02

  • 1 SMS segment = 160 characters

  • Long messages = multiple segments

  • Emojis, links, spacing, and special characters increase cost

Your exact cost may vary by country and carrier.


Why Messages Split Into Multiple Segments

Some characters force messages into a more expensive format.

Example Message (Real-World)

Hey [name] this is [name]! Can you message me directly and let me know what you want?  Here's what's for sale: Men’s Olympic Barbells Women’s Olympic Barbells Trainer Bars Axle Bars Barbell Trees (holds 11 bars) Concept2 Rower Rogue Bumper Plates York Bumper Plates Iron / Change Weight Plates Rogue V2 Bumper Plate Stackers Rogue Log Bar (LB-1 / LB-2) Medicine Balls Sleds (Rogue) Pyramid Plyo Boxes (12", 16", 20", 24") CFW Handmade Plyo Boxes (20 / 24 / 30") AbMats (older units) Rogue GHD Rogue Reverse Hyper

Segment Breakdown

  • Total characters: 507

  • Contains curly quotes ( ’ )

Because of those quotes:

  • The message is sent as Unicode

  • Unicode limit = 67 characters per segment

  • 507 ÷ 67 = 8 SMS segments

👉 This message is billed as 8 texts messages not 1 single SMS


How to Reduce SMS Cost

Replace curly quotes with straight quotes:

Men's Olympic Barbells Women's Olympic Barbells

Now the message uses standard GSM format:

  • 153 characters per segment

  • 507 ÷ 153 = 4 segments

✅ Same message, half the cost

Also note: your costs per SMS segment vary by region and country.


SMS Best Practices (Quick List)

Do This

  • Keep messages short

  • Use plain text

  • Use drip mode for groups

  • Send during business hours

  • Give people a clear way to opt out

Avoid This

  • ALL CAPS

  • Too many emojis or !!!

  • Long lists without spacing

  • Sending hundreds of texts at once

  1. Go to Contacts

  2. Choose or create a Smart List

  3. Select contacts

  4. Click Send SMS

  5. Turn on Drip Mode

  6. Set batch size and timing
