trigger custom_o_email on customobject__c(before insert)
{
if(trigger.isbefore && trigger.isinsert)
{
list<contact> clist= [select name,email,phone from contact];
map<string,string> emailstringmap=new map<string,string>();

for(contact c: clist)
{
if(emailstringmap.containskey(c.name)) {continue;}
else {emailstringmap.put(c.name,c);}
}

for(CustomObject__c temprec : trigger.new)
{
Contact tempC= emailstringmap.get(temprec.name);
temprec.email=tempC.email;
temprec.phone= tempC.phone;
}

}
}

I am assuming there are unique contact names and the duplicate rules are active under the contact object. Please make appropriate changes as needed.

Hi Akshay,

You can have a trigger on the custom object and implement it like below:
  
trigger custom_o_email on customobject__c(before insert)
{
if(trigger.isbefore && trigger.isinsert)
{
list<contact> clist= [select name,email from contact];
map<string,string> emailstringmap=new map<string,string>();

for(contact c: clist)
{
if(emailstringmap.containskey(c.name)) {continue;}
else {emailstringmap.put(c.name,c.email);}
}

for(CustomObject__c temprec : trigger.new)
{
String emailC= emailstringmap.get(temprec.name);
temprec.email=emailC;
}

}
}

Please note you need to modify it to fit your needs and you need to modify names as present in your org.

Additionally, I would suggest you to have a look at the best practices as well: https://developer.salesforce.com/forums/?id=906F0000000DBl8IAG

Hi Akshay Shrivastava,

If two contacts have the same name then out of 2 which contact email should be populated in the email field of the custom object?


Thanks & Regards
