Domain with sendinblue

[mstIT]

Hello! I have a domain that is on other VPS:

The Records are:

$ORIGIN example.xyz.
$TTL 1800
example.xyz. IN SOA ns1.digitalocean.com. hostmaster.example.xyz. 1488258634 10800 3600 604800 1800
example.xyz. 1800 IN NS ns1.digitalocean.com.
example.xyz. 1800 IN NS ns2.digitalocean.com.
example.xyz. 1800 IN NS ns3.digitalocean.com.
www.example.xyz. 1800 IN CNAME example.xyz.
mail._domainkey.example.xyz. 1800 IN TXT v=DKIM1; k=rsa; s=email; p=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA7WHyRbZHDvENlydpavBC4k536hD8bLyTa2ljNGLaN8LgH4WSG//GTpHMX667773EoFiWbcCCfiDnpUlGrc5Ozte0SwIi4Txuz+lA5TPQSVy5amgyvNg9yzo0x6m/Ki5UnR+PoLr0of5m1H/cL9/t5DNUoKdTe2yFcX4w3q3QD8sp32to1pNiaryRKR5C2RXzIjJY/N5VG078LOHX2JsMWknycnc+Os06n8tvUqgy0Va5o+iBDsLm9ypt59sLD3qKhFtlfH2jz7hRkv4cBtGuRDK5SpyBuSptvVBIfnQNhNab4se/SQqm7sMoIoUJdOxfJdZXBk+0YIHHYx5Cmux4nwIDAQAB

webmail.example.xyz. 1800 IN A 192.241.165.219
example.xyz. 1800 IN A 67.205.162.20

Everything goes fine. But I need to use SendInBlue service, so I open an account and try to authorize the domain. SendInBlue tells me that I need to add some records:

1. Add TXT record (DKIM) to "mail._domainkey.example.xyz“
   k=rsa;p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDeMVIzrCa3T14JsNY0IRv5/2V1/v2itlviLQBwXsa7shBD6TrBkswsFUToPyMRWC9tbR/5ey0nRBH0ZVxp+lsmTxid2Y2z+FApQ6ra2VsXfbJP3HE6wAO0YTVEJt1TmeczhEd2Jiz/fcabIISgXEdSpTYJhb0ct0VJRxcg4c8c7wIDAQAB

2. Add TXT record (SPF) to “example.xyz“
   v=spf1 include:spf.sendinblue.com mx ~all

3. Add TXT record to “example.xyz”
   Sendinblue-code:e2fdc72a614a4ddc36384905849650d8

4. Add TXT record (DMARC ) to “_dmarc.example.xyz”
   v=DMARC1; p=none; sp=none; rua=mailto:dmarc@mailinblue.com!10m; ruf=mailto:dmarc@mailinblue.com!10m; rf=afrf; pct=100; ri=86400

After adding those records, I’ve tried to send… but email testers tell me that I have two TXT records. What can I do to setup sendinblue and still use webmail (por pop/imap) without problem?

Thanks!
