Seven ways to replace Twilio, ranked on how well each one works from an AI assistant like Claude, ChatGPT, Cursor or Codex, for a team whose texts sit alongside its email. Nitrosend wins on email sent from the chat over MCP, with texting coming soon. For a cheaper SMS API alone, Telnyx is the pick.
Nitrosend is the best Twilio alternative for a team that runs its email from AI and wants texting in the same place once it arrives, with the top score of 76.5 out of 100 of the seven reviewed here. It scores 9 out of 10 on working from your AI assistant, the heaviest test, because its official MCP server lets Claude, ChatGPT, Cursor or Codex write email campaigns and flows from the chat. To send email from an AI assistant with Nitrosend, connect the MCP server at api.nitrosend.com/mcp with an OAuth sign-in: campaigns and flows stay drafts until they are approved, and a single receipt or other transactional email sends on the call. Twilio sells texting and email as two products on two bills. Nitrosend's texting is coming soon and is not open to customers today, so it replaces the email side now, with emails in your brand's colors, fonts and voice. Email costs $20 a month for 20,000 with unlimited contacts. Textmagic comes next at 53, then Telnyx at 50. If you need programmable voice, SIP trunking or carrier-level number management, no email platform does that, and Telnyx or Twilio itself is the answer.

7 services, the same 7 tests, 100 points in all. In order: Nitrosend 76.5, Textmagic 53, Telnyx 50, Postscript 34.5, SimpleTexting 31, SlickText 31, Plivo 25.5. Nitrosend has the best score on Works from your AI assistant, Emails in your brand, no designer, Free plan and Receipts and newsletters on one plan. Every price and feature was read on each company's own pages on September 26, 2026.
These scores measure email marketing run from an AI assistant, for a team that also sends texts. Nitrosend's texting is coming soon, so for texts you need to send today, and for programmable messaging, the services below are ahead of it. Read these before you choose.
Twilio's US rate is $0.0083 a text segment on a long code, toll-free number or short code, plus carrier fees and a number. Its email is SendGrid, a second product: Marketing Campaigns is $60 a month at 10,000 contacts on Advanced, the first plan with automation, and a quote above 200,000 contacts. The first table prices the email side of each alternative, at the volumes used on every email comparison on this site. The second shows 10,000 US texts a month, which is not scored, because not every service publishes a rate. Nitrosend has no text rate because its texting is not available yet.

Every service gets a score out of 10 on the same seven tests. Each test is worth a set number of points, 100 in all. These are the tests and points used on every email marketing comparison on this site, applied here to a team that sends email and texts. Working from your AI assistant and price are worth the most, 20 points each. The editor and the integrations, support and track record share 30 points.
Each test is a question with one answer per service, checked against the service's own pages on September 26, 2026. A 10 means it does the job fully on its normal plans. A 5 means it does part of it, or only on a higher plan or in a second product.
Works from your AI assistant, 20 points. Can an agent inside Claude, ChatGPT, Cursor or Codex compose a marketing campaign, test it, and send it, with no person opening the web app between the prompt and the send? An approval step the person answers in the chat counts as inside the agent. Moving into the web app to finish does not. Scored on one written rule for every vendor: a first-party server the vendor runs and that can send counts fully; a third-party wrapper (Zapier, Composio, Kanopi, community servers) counts for less; a server that only drafts or reads counts for less than one that sends.
Emails in your brand, no designer, 10 points. Does the product learn your logo, colors, fonts and voice from your own site and apply them to every email it drafts, on the plan most small teams start on?
Price, 20 points. What does email cost each month at 20,000 emails, a 10,000-contact list emailed twice, and at 1,000,000, a 500,000-contact list emailed twice? Scored on list prices in US dollars, paid monthly, at the cheapest plan that holds the contacts, covers the sends and includes automated emails such as a welcome series. Every ranking on this site uses the same fixed scale. At 20,000 emails, $20 or less scores 10, then $25 scores 9, $32 scores 8, $40 scores 7, $50 scores 6, $70 scores 5, $100 scores 4 and $140 scores 3. At 1,000,000, $500 or less scores 10, then $625, $800, $1,000, $1,250, $1,750, $2,500 and $3,500 step down the same way. Anything dearer, or a price given only by quote, scores 2. A free product scores 10. The score is the average of the two. A service that sells no email scores 0. Text message prices are shown in the price table but not scored, because not every service here publishes one. Nitrosend has no text rate because its texting is not available yet.
Free plan, 10 points. How far can a team get on the free plan before it has to pay: contacts, total sends, and the daily ceiling.
Receipts and newsletters on one plan, 10 points. Can receipts, password resets and newsletters go out from one account, on one bill, through one API?
Editor for building by hand, 15 points. For a person who wants to build the email themselves: how mature are the visual editor and the template library?
Integrations, support and track record, 15 points. How many tools does it plug into, what support comes with the plan, and how long has it been doing this at scale?
Scoring messaging APIs on email marketing tests is a choice, and it decides the order. Telnyx and Plivo have no editor, so they score 1 on the editor test. A service that sells no email scores 0 on price, whatever its text rate. If all you want is a programmable SMS API, Telnyx is the pick, and the order above does not change that. Text prices and inbox placement are not scored, and no test scores whether a service's texting is live. Nitrosend's texting is coming soon, so its score rests on the email side and the assistant alone, and the yes-or-no table marks its texting rows as not yet available. Twilio itself is not ranked, because this page is about what replaces it. Vonage is not scored because its US text rate could not be read on September 26, 2026.
Three things, and none of them is the API.
A2P 10DLC registration. Before a US long code can send application-to-person traffic, the brand and the campaign have to be registered with the carriers through The Campaign Registry. Every US provider enforces it. What Twilio owns is the experience: a queue you cannot see into, rejections that arrive as codes, and a number that works in testing and then does not in production. On October 2, 2026 Twilio's 10DLC fee page listed standard brand registration at $46 one-time, campaign vetting at $15, and a monthly campaign fee from $1.50 to $10 by use case. The same page says The Campaign Registry raised its standard fees on August 1, 2025 and now charges $12.50 for each retry of the Authentication Plus step for public, for-profit brands. That matters once an AI assistant files the paperwork: an agent that keeps retrying that step after an error pays on every attempt, so have it stop and show you the error after the first one.
Carrier fees that move without you. The $0.0083 base rate is not the number on your invoice. Twilio's US pricing page adds a per-segment carrier fee on a long code of $0.0035 at AT&T, $0.0045 at T-Mobile and $0.005 at Verizon, plus $0.001 on each failed message and the number rental, and says carrier fees change from time to time without notice. Twilio sat at 1.1 out of 5 on Trustpilot on October 2, 2026, and a Hacker News thread from October 2, 2024 summed up the developer side as "10DLC is a nightmare".
The bill is per segment, and a segment is not a message. A text over 160 standard characters, or over 70 with a single emoji or curly quote, bills as two. Twilio's own example is a 140-character message with one non-standard character, which splits into two segments. AI assistants write curly quotes, long dashes and ellipsis characters by habit, so a text your assistant drafted can cost double a text you typed. Twilio's Smart Encoding setting swaps some of those characters for plain ones. Before you move, ask whether the new service does the same, or tell your assistant to write straight quotes and plain hyphens in every text.
Texting on Nitrosend is coming soon. It is not open to customers today, and no launch date or text rate is published. What Nitrosend does today is email: campaigns, flows and single transactional emails, driven by an AI assistant over MCP, the same way it drives the email API. Campaigns and flows stay drafts until they are approved; a single transactional email sends on the call, as the MCP docs describe. Contacts are unlimited on every plan.
Text delivery and email deliverability are different systems, and if you send both you protect both.
For a team whose texts sit alongside its email, Nitrosend, with the top score here, 76.5 out of 100: email run from an AI assistant at $20 a month for 20,000, with texting coming soon. For a cheaper programmable SMS API, Telnyx. For a Shopify store, Postscript. For texting run by a marketer, SimpleTexting or SlickText.
On US list price it sits above Telnyx at $0.004 and Plivo at $0.0077, at $0.0083 a segment. Carrier fees are the same whichever provider you use, because they are the carriers' fees, and number rental and 10DLC fees come on top everywhere.
Nitrosend, with 9 out of 10 on working from your AI assistant. Its official MCP server writes email campaigns and flows from the chat as drafts that send once approved, and sends a single transactional email on the call; texting is coming soon. Textmagic scores 7: its MCP connector for Claude and ChatGPT sends and schedules texts to your lists and asks you to confirm each send, with the cost shown. Telnyx and Plivo score 5, because their MCP servers wrap the API with no campaign to send. EZ Texting also publishes an MCP server, and Twilio Labs publishes one that exposes Twilio's APIs. Check whether a send needs a person's approval, because an agent with unchecked send rights on a channel that costs money per message is a bill waiting to happen.
Add Nitrosend as a connector in Claude, ChatGPT, Cursor or Codex using its MCP server at api.nitrosend.com/mcp, and sign in with OAuth. Then ask in plain words, for example "send new sign-ups a welcome email, wait two days, then send a follow-up email". The assistant builds that as a flow draft, and nothing goes to your list until it is approved. A single receipt or other transactional email sends on the call. Texting is coming soon, so until it opens the texts stay on a separate service.
On Twilio's published ladder, read on October 2, 2026, $46 one-time for standard brand registration, $15 for campaign vetting, then a monthly campaign fee from $1.50 to $10 by use case. Twilio says it passes them through at no added cost, because the registry and the carriers set them, so they follow you to any provider. What differs is how much of the filing the provider does for you.
Not for programmable messaging. Nitrosend's texting is coming soon and is not open to customers yet, so it can replace SendGrid on the email side but not Twilio's texts today. It has no programmable voice, SIP, WhatsApp, RCS or number management. If your job is any of those, pick a communications platform.
Usually. US long codes and toll-free numbers can move between providers, short codes can too but more slowly and at more cost, and international numbers vary by country. Confirm each number before you sign.
Every plan includes full stack emailing: Flows, Newsletter Campaigns and Transactional Email, plus our NitroWheel LLM and all agent integrations (Claude, ChatGPT, Codex, Cursor and others). Pay for what you send, not who you store.
Every paid plan includes 3 agent inboxes and no Nitrosend footer.
