Open rates and speed

The defining difference is attention. Nearly every text gets read, and read quickly, because texting is where personal messages live. Email arrives in an inbox that sorts, batches, and buries; even a well-run list sees most messages go unopened.

That attention is why SMS wins anything time-sensitive: a shift that starts tomorrow, a flash sale ending tonight, a closure this morning. It is also why SMS must be used sparingly. The channel that interrupts is the channel people unsubscribe from fastest when it is overused.

Cost per message

Email is nearly free at the margin; SMS is metered per segment per recipient, typically a few cents each on credit plans (the full math is in the cost guide). On raw cost, email wins every time.

Cost per message read flips the comparison. An email blast to 10,000 people at a 25% open rate reaches 2,500 readers. A text blast to the same list reaches nearly all of them within the hour. For revenue-per-send on time-boxed offers, SMS routinely comes out ahead despite the higher unit price.

Content depth and format

Email holds a newsletter, a product grid, a long announcement. SMS holds one idea and one call to action inside a 160-character segment, with MMS adding a photo when it earns its extra credits.

The constraint is a feature: forced brevity produces messages people finish. But anything that needs comparison shopping, detailed terms, or scrolling belongs in email or on a landing page your text links to.

List building and consent

The legal bar differs by channel. US marketing texts need prior express written consent under the TCPA, with per-message statutory damages for getting it wrong. Email marketing under CAN-SPAM mainly requires honest headers and a working unsubscribe.

The practical effect: SMS lists grow slower but are far more engaged, because everyone on the list affirmatively asked to be there. Collect consent properly from day one (wording in the opt-in examples guide) and honor STOP instantly, and the channel stays healthy.

A useful test: would a reasonable person want this on their lock screen in the next five minutes? If yes, text it. If not, email it.

Using both together

Teams that run both channels well give each a distinct job:

  • Announce by email, close by text. Email carries the detail early in the week; a one-line text lands the deadline on the last day.
  • Remind by text what email confirmed. Booking confirmations by email, the 24-hour reminder by SMS (playbook in the appointment reminder guide).
  • Collect both opt-ins at sign-up, separately and clearly, so each channel's consent stands on its own.
  • Reserve SMS for what matters. A list that hears from you by text a few times a month stays subscribed; a list that gets daily texts evaporates.
