Comparison
SlickText 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
SlickText puts every feature on every plan and refuses to bill overage, which makes it a clean choice for a marketing list that fits a credit tier. It also stops publishing prices at 50,000 credits, bills carrier fees separately and does not publish seat pricing. Signilio also puts every feature on every plan, but publishes a price for every extra text, includes carrier fees and 2 to 15 seats by plan, and is built for outbound sales conversations rather than list marketing. For a team that keeps outgrowing its credit tier, the estimator below is the honest way to compare.

Where SlickText is the better fit
- List marketing with a strong automation toolkit: workflows, keywords and integrations on every plan, with no feature gating.
- No surprise overage: you are told when you run low and upgrade, which suits a fixed monthly budget.
- Price matching against SimpleTexting's standard plans and a 20% nonprofit discount.
Where Signilio is the better fit
- A published price for every extra text, 4¢ down to 3¢ by plan, so going over the allowance is a line on the bill rather than a forced upgrade.
- Carrier fees inside the rate, not billed in arrears.
- Seats published by plan, 2, 5 or 15; no seat price to ask about.
- A two-way team inbox built for assigning and closing replies, with 10DLC registration handled during onboarding.
Common questions
- Is SlickText 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, SlickText's cheapest published way to buy that is 10,000 credits, and the published bill comes to $361.00 a month before extra users (seat pricing not published) and 4 extra numbers and 10DLC campaign fee, which SlickText 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.
- Does SlickText charge overage?
- No. SlickText does not publish an overage rate; when you run low you upgrade to a larger plan, and with no credits you cannot send. On Signilio you buy extra texts any time at your plan's published rate, and they never expire.
- Are carrier fees included in SlickText's plans?
- No. SlickText passes carrier fees through separately, about $0.0042 per US SMS per its help center, billed in arrears. Signilio's plan price and extra-text price include them.
- How much does SlickText charge for extra users?
- It does not publish a per-seat price; team members can be added. Signilio publishes its seats: 2 on Starter, 5 on Growth and 15 on Pro.

- Onboarding is white-glove. We'll register your brand, configure your numbers, and get your first campaign out the door with you.
