Plans for every stage

Sends are blocked with an upgrade prompt. No surprise bills - ever. You can also buy credit top-ups (1,000 sends for $9, 5,000 for $35, 10,000 for $60) on any plan.

The 30-day trial includes 1,000 one-time sends, 500 contacts, 100 one-time AI calls, and a shared phone number. All channels (SMS, email, voice) are included. No credit card required.

SingleSend's shared pool sends only to phone numbers you've personally verified as your own (up to 5 per workspace). This keeps our platform compliant with carrier rules around shared messaging infrastructure. To send to your full contact list, register your own dedicated number - we'll guide you through the process from your settings.

Go to the contact page for the number, click "Verify ownership," and follow the 3-step flow: confirm the attestation, the recipient replies YES to a disclosure SMS, then enter the 6-digit code they receive. See our Terms for details on attestation requirements.

Each use of the AI assistant, message composer, smart send time, or sequence builder counts as one AI call. Pro and Business plans include unlimited AI calls.

Yes. Every paid plan includes 1 dedicated phone number. Additional numbers are $7/mo each. Trial accounts use a shared number.

Yes. On any paid plan you pick your own dedicated number - search by area code or city and pick from the available list. You can choose a local US number or a toll-free number (8xx). Toll-free numbers require carrier verification (~3-5 days) and have slightly higher per-message rates, but they skip 10DLC and work great for customer-support or broadcast use cases.

Yes, once every 90 days. We rate-limit number changes to protect deliverability and keep your messaging reputation stable with carriers. If you release a number, replies to it keep routing to your workspace for a 30-day grace period so nothing falls through the cracks.

Yes. Upgrade or downgrade anytime from your billing settings. Changes take effect immediately with prorated billing.

Every plan includes SMS, email, and voice messaging. Higher tiers unlock more sends, contacts, and advanced features like voice cloning, team inbox, and unlimited AI.

A custom sending domain lets you send emails from your own domain (e.g. you@yourcompany.com) instead of a shared one. It improves deliverability and brand trust. Available on all paid plans.

Every workspace gets a unique reply-to address (e.g. hello+your-company@m.singlesend.com). When contacts reply, their messages appear in your inbox automatically. If you have a custom sending domain, replies go directly to your domain email address instead.

No contracts. All plans are month-to-month. Cancel anytime from your settings - no questions asked.

Yes. SingleSend has a guided in-app wizard that walks you through 10DLC or toll-free carrier registration with major US carriers. We collect the required business info, validate it, and submit on your behalf. 10DLC takes ~10 min of paperwork plus 1-2 weeks for carrier approval; toll-free takes ~3-5 days.

Until you provision a dedicated number, your workspace uses our shared platform number. To protect carrier delivery quality for all customers, sending limits apply: trial workspaces get 20 SMS per day, paid workspaces without a dedicated number get 100 SMS per day, and once you have your own number on a paid plan you send freely under your plan's send limit. All workspaces on shared infrastructure are capped at 3 SMS to the same recipient within any 24-hour period. Limits double on shared when you've added a verified business website (privacy policy required). For unrestricted volume, complete 10DLC registration or toll-free verification and use a dedicated number.

Each user who sends SMS must verify their personal phone via a one-time code (OTP). It is a one-time per-user check that helps us prevent abuse and stay compliant with US carrier requirements. We send up to 3 OTP codes per phone number per hour. The verification persists across sessions, so you only do it once per device-trusted user.

Before your workspace can send SMS, the workspace OWNER (not members) must accept a one-time attestation confirming you have proper opt-in for your contacts and will honor STOP keywords. This is a US carrier requirement applied uniformly across the industry. It takes about 30 seconds in Settings and you only do it once per workspace.

We run a lightweight pre-send classifier on shared-pool SMS to catch obviously spam-shaped messages (links to suspicious shorteners, urgent-action language, etc) before they damage your sender reputation. If the classifier blocks a message you think is fine, you can appeal it inline (5 appeals per hour) and a real human reviews it. Workspaces sending from a dedicated number after carrier registration are exempt from automated classification.

While you're using our shared platform number, we cap sends at 3 SMS to the same recipient within any 24-hour window. This prevents one workspace's high-velocity messaging from getting the entire shared pool flagged by carriers. Once you provision a dedicated number after 10DLC or toll-free registration, the per-recipient pacing cap no longer applies and you send freely under your plan limit.

US mobile carriers (T-Mobile, AT&T, Verizon) require all business SMS senders to register with The Campaign Registry (TCR). Without registration, carriers heavily filter or silently drop messages - typically 30-40% non-delivery on T-Mobile alone. The registration ties a sender brand and use case to a phone number, lets carriers verify legitimate business traffic, and gives you reliable delivery plus higher throughput. We collect this info to register you with TCR; it is not used for any other purpose. See our Privacy Policy for full details.

Yes. T-Mobile, AT&T, and Verizon require all business SMS senders to register - without registration, carriers heavily filter or silently drop messages. SingleSend offers two paths: 10DLC (local number) is best for businesses with an EIN, gives you a local number with full throughput, and takes ~10 min of paperwork plus 1-2 weeks for carrier approval. Toll-Free Verified is for solo consultants and businesses without an EIN, gives you a toll-free number, and takes ~3-5 days for approval. Until you complete registration, you can use our shared platform number with daily limits (see Fair Use).

Use the Toll-Free Verified path. It only requires a business name, address, a live website, and a description of your opt-in workflow - no EIN needed. Approval typically takes 3-5 days and gets you a 1-800/833/844-style toll-free number with solid carrier delivery. If you'd prefer 10DLC for branding reasons, you can form an LLC (~$100 plus 1 hour at your state's Secretary of State website), then register with your new EIN.

Don't worry - we've got you covered. When you delete a contact, it's soft-deleted, meaning it's recoverable. Your data stays safe, and our support team can restore any accidentally deleted contact in seconds. No data is ever permanently lost without your explicit confirmation.

Absolutely. We snapshot every contact before a merge, so if you realize you merged the wrong records, our support team can undo it completely - restoring the original contacts with all their data intact. It's like a safety net for your contact management.

Every SingleSend account comes with AI-powered instant support built right into the app. Ask questions, get help with setup, or troubleshoot issues - all without leaving your dashboard. Need human help? One click escalates to our team with full context, so you never have to repeat yourself.

Your billing records are securely retained for 7 years (as required by law), but all personal data, contacts, messages, and workspace data are permanently deleted when you close your account. You can export everything first with one click - we make it easy to take your data with you.

Yes! Every new account starts with a free trial that includes the same features as our Starter plan - 1,000 messages, 500 contacts, and full access to AI-powered compose, inbox, and analytics. No credit card required. See the value before you commit.

Share your unique referral link with friends and colleagues. When they sign up and subscribe to a paid plan, you both win - you get bonus send credits added to your account automatically. The more people you refer, the more you send for free.

Security isn't an afterthought at SingleSend - it's foundational. All personal data is encrypted at rest with AES-256-GCM (the same standard banks use). We verify every webhook with cryptographic signatures, enforce role-based access across your team, and maintain comprehensive audit logs so you always know who did what.

Yes - SingleSend is built for teams. Invite members with granular roles (Owner, Admin, Manager, Member), assign inbox threads automatically with round-robin, leave internal notes with @mentions, and track team workload from your dashboard. Collaboration is a first-class feature, not a bolt-on.
