CallHub uses pay‑as‑you‑go pricing with no setup fee, and your current baseline is roughly 4¢ per outbound text in your internal comparison. GetThru’s ThruText pricing has historically been higher on a per‑message basis (often around 8¢ per outbound SMS in common contract tiers), and many contracts include a setup fee (e.g., $100) to start.

GetThru’s current public materials emphasize billing per outgoing message/segment and note “unlimited incoming messages” on some partner pricing pages, but actual terms can vary by contract. In your internal comparison, you are assuming roughly 8¢ per incoming text for ThruText versus approximately 1.2¢ per incoming text on CallHub, which is consistent with CallHub’s lower inbound SMS costs.

Because GetThru’s exact inbound pricing depends on each contract, it’s safest to verify the inbound rate on your own agreement.

GetThru (ThruText/ThruTalk) is built around a browser-based interface, where volunteers log in from laptops or desktops to text or call. There is no dedicated mobile app for agents to join campaigns via a native iOS/Android experience.​

CallHub, by contrast, offers native mobile apps so volunteers can join campaigns and take part in phone banking or outreach directly from their smartphones, in addition to using a web browser.

• CallHub – account creation is self‑serve and instant; campaigns can typically import a list and launch their first calling or texting campaign in just a few minutes.

• GetThru (ThruText/ThruTalk) – onboarding is contract-based. Setup often happens after paperwork and any setup fee are handled, and teams may need more time to configure programs and train admins before launch.

For fast-moving campaigns that need to test quickly or spin up last‑minute outreach, CallHub’s self‑serve model is usually faster to start.

GetThru rents numbers for use during active campaigns but generally does not give customers fine‑grained control over exactly which numbers are assigned or allow them to keep the same numbers across unrelated campaigns.​

CallHub allows you to rent specific numbers, choose area codes, and keep those numbers across campaigns for as long as you pay the monthly fee (e.g., around $5/month per number), which is helpful for brand consistency and long‑term organizing.

GetThru is primarily focused on US and limited international use cases and does not support all countries (for example, Australia has been explicitly unsupported in some cases).​

CallHub supports calling and texting in over 190 countries, which makes it a better fit for international campaigns, global nonprofits, and diaspora organizing.

• CallHub – no setup fee; you can sign up, get free credits, and start immediately.​

• GetThru – typically includes a setup fee (commonly cited around $100) in contracts for ThruText/ThruTalk, though exact amounts can vary by agreement and program size.
