Integrations
Connect your tools with your own keys.
Bring contacts and product events in, send through your own provider, and pass events back to your systems. Each integration shows its real status, what it needs and what Sendalto does with it.
- Available
- Works today with your own account.
- After review
- Connect and send tests today; real sending after Sendalto’s business review and on a paid plan.
- Coming soon
- Not switched on yet.
Data in
Contacts and product events.
Who your people are, what they agreed to, and what they do in your product.
CSV import
AvailableContacts and consent
Bring in contacts together with where they came from and what they agreed to.
You provide
- A CSV file up to 1.5 MB — up to 5,000 rows and 100 columns
- An email column; optional consent columns: purpose, basis, source, proof, granted and date
What Sendalto does
- Shows a mapping preview with sample rows and problems before anything is saved
- Records consent per person with its source and proof
- Never re-adds an address that is on the do-not-contact list
Events API
AvailableProduct events
Send product events — signed up, trial started, upgraded — so journeys start and stop at the right moment.
You provide
- An API key with the events scope, called from your server
- For each event: a unique ID, a name, the person’s email, optional properties and time
What Sendalto does
- Starts journeys on trigger events and ends them when the goal event arrives
- Ignores a repeated event ID, so retries are safe
- Accepts up to 600 events a minute per workspace
HubSpot
AvailableCRM contacts and companies
Keep contacts and companies in step with your CRM, and hand a warm conversation over to sales.
You provide
- A HubSpot private app access token that can read contacts and companies
- Write access only if you turn on handoff to the CRM
What Sendalto does
- Imports contacts and companies; your local fields win unless you let the CRM own them
- Turns a HubSpot email opt-out into a Sendalto opt-out and cancels queued sends
- Writes back only when a person hands a contact off — as a note, with an optional owner
Being in your CRM isn’t consent to marketing email.
API keys
AvailableServer access
Let your own systems send events and work with contacts, companies, segments and campaigns.
You provide
- An owner or admin with two-factor authentication creates the key
- One to five scopes: events, contacts (read or write), campaigns (read or write)
What Sendalto does
- Shows the key once and stores only its hash
- Records every request made with a key
- Never lets a key approve or send a campaign
Your systems
Events back out, files kept private.
Pass what happens in Sendalto to your stack, and keep workspace files in a bucket you own.
Webhooks
AvailableEvents to your systems
Forward the events you choose — including HubSpot contact and company changes — to your own endpoint.
You provide
- A public HTTPS address
- The names of the events you want, up to 50
What Sendalto does
- Signs every delivery with HMAC-SHA256 and a timestamp
- Retries a failed delivery up to 8 times, with growing pauses
- Lets you rotate the secret, pause the webhook or retry a delivery
Amazon S3
AvailableWorkspace files
Store workspace files — images, PDFs, CSV and text files — in your own private bucket.
You provide
- AWS access keys, a region and a bucket with Block Public Access fully on
- Bucket CORS that allows uploads from Sendalto
What Sendalto does
- Refuses a bucket that is public in any way
- Uploads files up to 10 MB through short-lived signed links, encrypted at rest
- Hands out download links that expire after 60 seconds
Sending and replies
Your domain, your mailbox.
Sendalto sends through providers you own: lifecycle email through Amazon SES, B2B outreach through your own mailbox.
Amazon SES
After reviewLifecycle sending
Send lifecycle and marketing email to people who agreed to hear from you, from your own verified domain.
You provide
- An AWS account with SES production access
- AWS access keys, a region and your sending domain
- DKIM, custom MAIL FROM and DMARC records, plus an SNS topic for bounces, complaints and deliveries
What Sendalto does
- Creates the SES resources for your workspace and lists the DNS records to add
- Checks domain, DKIM, MAIL FROM, DMARC, quota and feedback before use — and again before each send
- Turns bounces and complaints into opt-outs; a complaint pauses sending until reviewed
Connect it and send test emails to your own address today. Real sending starts after a business review and on a paid plan — plans aren’t on sale yet.
SMTP / IMAP
Coming soonOutreach mailbox
Send B2B outreach from a mailbox your company owns, and read the replies in Sendalto.
You provide
- The mailbox address, SMTP (465 or 587, TLS) and IMAP (993) servers, a username and an app password
- Confirmation that your company owns the mailbox and your provider allows this use
- A separate outreach review by Sendalto
What Sendalto does
- Sends outreach only from that mailbox — never through Amazon SES
- Pauses a sequence when someone replies, until a person reviews it
- Applies limits per person and per company
Not switched on yet: outreach mailboxes open once we’ve approved the first mail providers.
Gmail
Coming soonMailbox replies
Read replies in your Gmail mailbox and answer them one by one from Sendalto.

Microsoft 365
Coming soonMailbox replies
Read replies in your Microsoft 365 mailbox and answer them one by one from Sendalto.
You provide
- Sign-in with Microsoft for your own mailbox — shared mailboxes aren’t supported
- Permission to read and send mail; your organisation may require admin consent
What Sendalto does
- Sends only individual replies to people who wrote to you — never campaigns or outreach
- Keeps mailbox content out of marketing personalisation and AI
- Erases the saved access when you disconnect
How connections work
Your credentials, checked before use.
Every connection uses your own account. Sendalto checks it against the real provider before relying on it.
Checked, sealed and easy to cut off
Owners and admins connect providers in Settings → Integrations. Credentials are encrypted when saved and never shown again. A connection check runs against the real account, and a check older than 24 hours blocks sending until it passes again.
- New credentials reset the check and cancel queued sends
- Disconnecting erases the saved keys and releases reserved budget
- Changing a connection needs two-factor authentication
Sendalto is not affiliated with these companies. Product names belong to their owners.
Bring your data, keep your keys.
Setting up and connecting your tools is free, and nothing is sent without your approval.
