Send Bulk SMS People Actually Want to Receive

Bulk SMS gets read fast — but it's also easy to get wrong. Here's how to send a bulk text campaign in Vendi Today, and how to keep it from feeling like spam.

Sending a bulk SMS campaign

Select the contacts you want to message — from a list, a smart list, or a saved segment.
Click Send SMS.
Write your message and give the campaign a title for your own reference.
Choose how it goes out:
- Send all at once — everyone gets it immediately.
- Send at a scheduled time — everyone gets it at a future date/time you set.
- Drip mode — messages go out gradually in batches rather than all at once.

Configuring drip mode

If you choose drip mode, you can set:

A start date and time
How many messages go out per batch
How often batches repeat
Which days of the week sends are allowed
An optional send window (for example, only between 10:30 AM and 11:00 AM)

Drip mode is useful for large lists — it spreads sends out so replies come in at a manageable pace instead of all flooding in at once.

Staying compliant

Only text people who've given you consent to receive messages.
Identify your business by name in the message.
Include opt-out language ("Reply STOP to opt out") on your first message to a contact, or again if it's been 90+ days since your last one.
Honor STOP requests immediately and don't message that contact again.

Getting better response rates

Personalize with the contact's first name using a merge field rather than sending something generic.
Don't over-send — once a month is a reasonable ceiling for broad campaigns.
Keep the tone short, casual, and low-pressure; skip excessive punctuation or emojis.
Lead with a clear offer or reason to respond.
Ask one direct question rather than several, so replies are easy to give.
Avoid including links where possible — links can hurt deliverability and trigger spam filters.
Reply quickly when people respond — slow replies make a legitimate campaign look like a bot or spam operation.
