Sendblue vs SimpleTexting (2026): which should you pick?

Pick Sendblue if

• Fits if a developer wants iMessage from an AI agent or app
• Works for teams wiring messages into a CRM

Look elsewhere if

• Tight if you want outbound messaging, as the $100 plan is inbound-first with 1,000 contacts a day
• Skip it if you want a working free plan, as the sandbox is for testing only
• Pricey if you need many lines, as each is $100 and annual billing goes through sales
• Watch out: iMessage reaches Apple devices only
• Not for you if you do not code, as it is an API

Pick SimpleTexting if

• Fits if you're a small US business sending promotions and reminders by text
• Works for churches and nonprofits, with 15% off monthly plans

Look elsewhere if

• Not for you if your customers are on WhatsApp or Instagram rather than plain texts
• Pricey if your team is big, as each user past 3 costs $20 a month
• Tight if you downgrade, as rolled-over credits are lost when you do
• Watch out: a local number adds $10 a month and $4 to register, and carriers add about $0.0025 per US text
• Pricey if you want a dedicated short code, from $1,000 a month with 6 to 8 weeks to set up
