This guide walks you through adding the required DNS records in IONOS to verify your domain with Flowforth.
Before starting, make sure you’ve already added your domain in Flowforth. You’ll need the DNS record values shown on the domain settings page.

​
Open DNS Settings in IONOS

  1. Log in to your IONOS account
  2. Choose your domain from the Domain list
  3. Select the DNS tab to manage DNS records

​
Add the MX Record

Click Add record:
  1. Select MX as the record type
  2. Enter the name from Flowforth (e.g., send) in the Name field
  3. Copy the MX Value from Flowforth into the Points to field
  4. Set the Priority to 10
  5. Use the default TTL of 1 hour
  6. Click Save
IONOS automatically appends your domain to the Name field. Enter only the subdomain portion — for example, type send instead of send.example.com.

NameNamesend
Points toValuefeedback-smtp.us-east-1.amazonses.com
PriorityPriority10
TTL—1 hour
If priority 10 is already in use on another MX record, use a different value like 20 or 30.

​
Add the SPF Record (TXT)

Click Add record:
  1. Select TXT as the record type
  2. Enter the name from Flowforth (e.g., send) in the Host name field
  3. Copy the TXT Value from Flowforth into the TXT value field
  4. Use the default TTL of 1 hour
  5. Click Save
IONOS automatically appends your domain to the Host name field. Enter only the subdomain portion — for example, type send instead of send.example.com.

​
Add the DKIM Record (TXT)

Click Add record:
  1. Select TXT as the record type
  2. Enter the DKIM name from Flowforth (e.g., resend._domainkey) in the Host name field
  3. Copy the DKIM Value from Flowforth into the TXT value field
  4. Use the default TTL of 1 hour
  5. Click Save
IONOS automatically appends your domain to the Host name field. Enter only resend._domainkey instead of resend._domainkey.example.com.

Host nameNameresend._domainkey
TXT valueValuep=example_domain_key_value
TTL—1 hour

​
Add the DMARC Record (TXT)

While not strictly required, adding a DMARC record is highly recommended. It improves deliverability and protects your domain’s reputation.
If your domain already has a DMARC record, you do not need to add another one. You can check by looking for an existing TXT record with the name _dmarc in your IONOS DNS records.
Click Add record:
  1. Select TXT as the record type
  2. Enter the DMARC name from Flowforth (e.g., _dmarc) in the Host name field
  3. Copy the DMARC Value from Flowforth into the TXT value field
  4. Use the default TTL of 1 hour
  5. Click Save
IONOSFlowforthExample Value
TypeTypeTXT
Host nameName_dmarc
TXT valueValuev=DMARC1; p=none;
TTL—1 hour

​
Add the Tracking Records (Optional)

If you enabled click tracking or open tracking when adding your domain in Flowforth, you’ll need to add these two additional records. You can also enable tracking later from the domain detail page in Flowforth — the records will appear in your DNS table when tracking is turned on.

​
CNAME Record (Tracking)

Click Add record:
  1. Select CNAME as the record type
  2. Enter links in the Host name field
  3. Enter links1.resend-dns.com in the Points to field
  4. Use the default TTL of 1 hour
  5. Click Save

​
CAA Record (Tracking)

Click Add record:
  1. Select CAA as the record type
  2. Enter your domain in the Host name field
  3. Set the Tag to issue
  4. Enter amazon.com in the Value field
  5. Use the default TTL of 1 hour
  6. Click Save

​
Verify in Flowforth

Once all records are added in IONOS, go back to your domain in Settings → Domains and click the “Records Added” button. Flowforth will check your DNS records and verify the setup in the background.
DNS changes can take anywhere from a few minutes to several hours to propagate. If verification doesn’t succeed right away, wait and try again later.

​
Troubleshooting

  • Verification failed: Double-check the records you added in IONOS for copy/paste errors. Make sure you’re using only the subdomain portion in the Name/Host name field (e.g., send not send.example.com).
  • Priority conflict: If priority 10 is already in use on another MX record, use a different value like 20 or 30.
  • Still not verifying after 72 hours: Contact support@flowforth.co and we’ll help you debug the issue.
