Comparison
Textline pricing vs Signilio for sales teams
Published pricing, what a plan includes, the fees that show up later, and the shared inbox, side by side. Checked September 25, 2026.
The short answer
Textline is a well-built shared inbox for support and sales teams, sold as a monthly plan with a few agents and a few hundred credits included, and priced so that seats are the real cost: $50 to $70 a month per extra agent, $15 a month per campaign and per extra number, and credits that expire at the end of the cycle. Signilio includes 2 to 15 seats by plan, extra numbers at $1 and texts priced in dollars, from $34.99 a month for 1,000. On Textline's entry plan the included credits work out to about 25 cents a message and add-ons are 3 cents; for a sales team with several reps sending at volume, the estimator shows the difference.

Common questions
- Is Textline cheaper than Signilio?
- It depends on volume and team size. For a team of five sending 10,000 one-segment texts a month from five numbers, Textline's cheapest published way to buy that is Essentials, and the published bill comes to $606.00 a month before carrier fees, which Textline does not price publicly. Signilio is $189.99 a month on its Pro plan for the same team, carrier fees included. Which one is cheaper changes with volume and team size, so the calculator above gives your own number.
- How much does Textline cost?
- Its pricing page does not show prices; its help center lists Essentials at $149 a month with 3 agents and 600 credits and Pro at $349 with 5 agents and 2,000 credits, month to month, with extra agents at $50 or $70. Signilio's Growth is $79.99 a month with 5 seats and 3,000 texts; Pro is $189.99 with 15 seats and 12,000.
- Do Textline credits roll over?
- Included plan credits expire at the end of the billing cycle; add-on credits bought in advance at $0.03 never expire. On Signilio the texts a plan includes reset on the 1st of each month, and extra texts are bought at the plan's rate and never expire.
- Does Textline charge for 10DLC?
- Brand registration is covered for accounts with fewer than 50 numbers; campaigns are $15 a month each. Signilio registers you during onboarding, with no separate campaign fee on its plans.
